Dimension and crushed stones

General information and occurrence

The group of mineral raw minerals, assigned in “The balance…” to the dimension and crushed stones (other name: road and building stones) comprises 33 lithological varieties of igneous, sedimentary and metamorphic rocks displaying properties which make them useful in a domestic economy. The stones meeting the appropriate requirements are used for the production of crushed aggregates – a high-grade raw material for the building, road and railway construction and stone elements for the road construction (stone for paving roads, stone and stone plates for sidewalks, stone street curbing and curb ramps) and the building construction (stone blocks, decorative plates for elevation and facade, floor plates and slabs).

Deposits of the igneous and metamorphic rocks occur mainly in the southern part of Poland – in the area of the following Voivodeships: Dolnośląskie (basalts, granites, granodiorites, syenites, diabases, gabbros, melaphyres, porphyres, porphyric tuffs, amphibolites, serpentinites, greenstones, gneisses, migmatites, crystalline schists, marbles), Opolskie (basalts, granites, gneisses, marbles) and Małopolskie (diabases, melaphyres, porphyres and porphyric tuffs). Sedimentary rocks are much more common. Limestones and dolomites form numerous deposits located in the area of Dolnośląskie, Łódzkie, Małopolskie, Śląskie and Świętokrzyskie Voivodeships, sandstones in the area of Dolnośląskie, Łódzkie, Małopolskie, Podkarpackie, Śląskie and Świętokrzyskie Voivodeships, whereas limestones, opokas and marls in the area of south-eastern Poland Voivodeships (Lubelskie and Podkarpackie).

The location of dimension and crushed stones deposits is presented on two separeted maps - for South-Western Poland and for South-Eastern Poland.

Resources and output

The anticipated economic resources of dimension and crushed stones as of the end of 2020 amounted to 11,521.44 million tonnes. They decreased by 21.81 million tonnes, that is by 0.19% in comparison with the previous year. The number of deposits dropped from 742 to 741 – 5 new deposits were documented, 3 deposits crossed out in 2019 not included in “The balance…”, 3 deposits reassigned to the raw materials for cement and lime industries. The most numerous are the sedimentary rocks deposits represented – by 542 deposits accounting for 69.7% of the total deposits number. The number of the documented igneous rocks deposits is equal 174 (accounting for 22.3% of the total deposits number), whereas the metamorphic rocks deposits amount to 62 (accounting for 8.0% of the total deposits number).

The anticipated economic resources of sedimentary rocks represent 47.8% of the total resources (5,510.41 million tonnes), of igneous rocks 39.6% of the resources (4,564.10 million tonnes) and of metamorphic rocks 12.6% (1,446.93 million tonnes). In comparison with the previous year, the most significant resources growth was recorded for the igneous rocks i.e. by 77.50 million tonnes (it means by 1.73%) – mainly due to the increases within granites and porphyres. The resources of the sedimentary and metamorphic rocks decreased by 92.04 million tonnes (1.64%) and by 7.27 million tonnes (0.50%), respectively.

About 53.9% of the anticipated economic resources of the given group of raw materials i.e. 6,213.74 million tonnes include 316 exploited deposits (exploited continuously and temporarily). Within the group of non-exploited deposits there are 200 deposits covered by the detailed exploration with the resources equal 2,594.09 million tonnes (accounting for 22.5% of the total resources) and 47 deposits covered by the preliminary exploration with the resources equal 1,778.73 million tonnes (accounting for 15.5% of the total resources). The resources of 178 deposits in which the exploitation was abandoned amount to 934.87 million tonnes accounting for 8.1% of the total geological resources of the dimension and crushed stones.

Table 1 shows the current state of the exploration and development of the dimension and crushed stones.

The economic resources amounted to 3,679.11 million tonnes in 2020 increasing by 105.84 million tonnes (3.0%) in comparison with 2019. These changes resulted from the elaboration of new deposit development plans and supplements to such plans, and also from the exploitation and losses.

The anticipated economic resources of dimension and crushed stones drop was the result of:

  • the change of the raw material usage in 3 deposits with total resources equal 127.09 million tonnes: the Devonian limestones, marly limestones and marls deposit Stobiec (92.37 million tonnes), the Jurassic limestones deposit Raciszyn (25.53 million tonnes) and Raciszyn II (9.19 million tonnes) – the resources of these deposits since 2020 are the raw material for the cement and lime industries and are described in a separate chapter;
  • the ongoing exploitation (65.56 million tonnes);
  • the changes of documentation boarders together with the resources updating and the resources settlement due to the exploitation end (the total drop by 10.05 million tonnes) – the basalt deposit Księginki-Północ (the drop by 3.66 million tonnes), the Triassic limestones and dolomites deposit Imielin-Rek (the drop by 3.63 million tonnes), the limy dolomite and crystal marble deposit Góra Apla (the drop by 1.65 million tonnes), the Devonian limestones deposit Łagów IV (the drop by 0.89 million tonnes), the Krosno sandstones deposit Miłkowa (the drop by 0.12 million tonnes) and the Devonian limestones deposit Łagów V (the drop by 0.09 million tonnes);
  • the updating and recalculation of resources, the better deposits exploration and the settlement of the exploitation losses – the total drop by 3.65 million tonnes;
  • the crossing out Żarnów sandstones deposit Pilichowice I (the drop by 0.04 million tonnes).

The anticipated economic resources growth was connected with the documentation of new deposits, the extending of existing deposits borders, the more detailed exploration of the deposits and the reclassification and verification of the resources. The resources increase due to:

  • the extension of the deposits areas or the deepening of their range and the updating of the resources amount (the total resources growth by 145.60 million tonnes): the granite deposit Zimnik I (the growth by 27.12 million tonnes), the porphyry deposit Zalas (26.39 million tonnes), the Triassic limestones deposit Szymiszów (20.56 million tonnes), the granite deposit Goczałków (18.26 million tonnes), the basalt deposit Winna Góra (12.28 million tonnes), the granite deposit Strzeblów II (10.66 million tonnes), the dolomite and limy dolomite deposit Komorniki 1 (10.34 million tonnes), the granite deposit Wieśnica (5.69 million tonnes), the basalt deposit Księginki I (3.87 million tonnes), the Krosno sandstones deposit Porąbka (3.82 million tonnes), the Magury sandstones deposit Chomranice (3.07 million tonnes), the basalt deposit Sulików (2.92 million tonnes) and the Devonian limestones deposit Łagów III (0.51 million tonnes);
  • the including 5 newly documented deposits into “The balance…” with the total resources equal 47.15 million tonnes – the Devonian limestones deposit Krępa (the growth by 33.72 million tonnes), the Devonian limestones deposit Nowy Staw II (11.34 million tonnes), the limy dolomite and marble deposit Góra Apla 1 (1.47 million tonnes), the Miocene limestones deposit Smerdyna (0.40 million tonnes) and the menilite schists deposit Ulanica-1 (0.23 million tonnes);
  • the more detailed exploration, the resources reclassification and recalculation, the current verification and updating of resources at the level of 2.83 million tonnes.

According to the data provided by the concession holders of the exploited deposits, the output of dimension and crushed stones amounted in 2020 to 76.56 million tonnes and decreased in comparison with 2019 by 2.15 million tonnes (2.73%). In terms of the output volume, the most important are the sedimentary rocks: limestones and dolomites – accounting for 44.48% of the total domestic output, and sandstones – accounting for 11.17% of the total output. Among the igneous rocks the granites, basalts and melaphyres are being exploited in the greatest amounts – accounting for 13.50%, 8.84% and 5.53% of the total output, respectively. The metamorphic rocks are of the minor importance considering the output of solid rocks (the total share of the domestic output of 9.16%). In comparison with 2019, the output of sedimentary rocks decreased by 0.85% (0.37 million tonnes), whereas that of metamorphic rocks by 7.09% (0.53 million tonnes). The output volume of igneous rocks decreased by 4.50% (1.24 million tonnes) and the drop covered almost all of the lithological types of these rocks (melaphyres, gabbros, basalts, porphyres and diabases).

The rock mining is concentrated within the area of 2 Voivodeships: Dolnośląskie which accounts for 40.8% of the domestic output of the dimension and crushed stones (260 deposits and 51.8% of the domestic resources) and Świętokrzyskie with the share in the total output of 34.5% (142 deposits and 21.7% of the domestic resources). Then comes Małopolskie Voivodeship accounting for 12.0% of the total output (103 deposits and 11.2% of the domestic resources) and the following Vivodeships: Śląskie (5.0% of the domestic output), Opolskie (4.2%), Podkarpackie (2.8%) and Łódzkie (0.6%). The shares of the remaining Voivodeships do not exceed 0.1%.

Dimension and crushed stones are also obtained during the brown coal exploitation. In 2020 there were 1.99 thousand tonnes of erratic boulders, 3.43 thousand tonnes of quartzites and 769.19 thousand tonnes of limestones exploited in KWB Bełchatów SA mine (the Szczerców field).

The figure given below shows changes in domestic resources and production of dimension and crushed stones in Poland in the years 1989-2020.

Table 2 shows the current state of exploration and development and production with breakdown of individual lithological types of rocks used in road and building construction.

The resources volumes, the state of deposits development and the output amounts divided into the lithological types of rocks documented as dimension and crushed stones are presented in Table 3.

The prospective resources of dimension and crushed stone were assessed to be equal about 36,921 million tonnes, whereas the biggest resources are located in the area of Małopolskie Voivodeship (53.4% of the total resources), Świętokrzyskie Voivodeship (16.4% of the total resources), Śląskie Voivodeship (13.0% of the total resources) and Dolnośląskie Voivodeship (10.7% of the total resources)*. The assessed prognostic resources of dimension and crushed stones amount to about 33,208 million tonnes and their occurrence is concentrated in Dolnośląskie Voivodeship (82.3% of the total resources) and Śląskie Voivodeship (13.4% of the total resources). The prospective and prognostic resources are concentrated mainly within the area of 4 Vovivodeships: Dolnośląskie, Małopolskie, Śląskie and Świętokrzyskie, which is in line with the current mining centers of this raw material from documented deposits. With regard to lithology, the largest resources are formed by the sedimentary rocks (32,867 million tonnes of prospective resources and 5,845 million tonnes of prognostic resources – these are mainly sandstones, limestones and dolomites), then metamorphic rocks (765 million tonnes of prospective resources and 23,905 million tonnes of prognostic resources – mainly gneisses) and then – igneous rocks (3,289 million tonnes of prospective resources and 3,458 million tonnes of prognostic resources – mainly granodiorites and granites).
