Dawny kamieniołom wapienia w Leszczynie EarthCache

Na spękaniach skał można zauważyć dendryty, czyli manganowo-żelaziste naloty przypominające rysunki roślin. Dendryty kształtem przypominają rozgałęzione drzewo, krzew lub liść paproci. Ze względu na podobieństwo do roślin, dendryty w minerałach bywają mylone ze skamieniałościami roślinnymi. Nazwa pochodzi od greckiego słowa δενδρον (déndron), oznaczającego 'drzewo'.

1. Czy dendryty występują tylko na skałach wapiennych?
2. O czym świadczą możliwe do zaobserwowania odciski muszli?
3. Znajdź miejsce przedstawione na zdjęciu i oszacuj długość zaznaczonego fragmentu:

Former limestone quarry, closely related to the twin metallurgical furnaces, currently located in the Mining and Metallurgical Heritage Park Dymarki Kaczawskie.
The quarry has been operated in the nineteenth century present appearance of the quarry shows how the rocks were cut for further processing. Mined in the excavation of limestone blocks were transported in wagons down to the furnace and there burned to lime.

In the quarry there are gray-yellow marly limestone and light gray dolomitic. Impressive is easily visible sediment layer system, documenting how to create this place in the ground.
The dolomitic limestone addition has a significant share of calcite dolomite (it was the result of precipitation from sea water in chemical processes with the participation of the animal world).

For cracks of rocks can be seen dendrites, or ferruginous manganese raids like drawings of plants. Branched dendrites resemble the shape of a tree, shrub or fern leaf. Due to the similarity of the products, dendrites in the minerals tend to be confused with plant fossils. The name comes from the Greek word δενδρον (Dendron), meaning 'tree'.
