Open quarry on the eastern slopes of the hill Łazek 225m, revealing the contact zone of the Strzegom Sobótka Massif granodiorites with hornfels and marble inserts.

Petrology:
- medium-crystalline, porphyritic hornblende-biotite granodiorite
- fine-crystalline augite-hornblende-biotite tonalite (Majerowicz, 1966; Turniak et al., 2014).

First discovery of MgAl2O4 in situ in Poland. Łobos at all - Abstract:
The study identified spinel crystals within a marble interlayer contained in hornfels. Spinel occurs in the form of perfect octahedrons of violet color. The crystals reach a size of up to 2 mm, but typically are much smaller. The hornfels zone with a calc-silicate rock and a marble inlayer is about a dozen meters thick and most probably comes from the metamorphic cover of the Strzegom batholith.
