Description
Pitchstone is a dark coloured, glassy volcanic rock formed when felsic lava or magma cools quickly. Since it is a volcanic glass, pitchstone may have a conchoidal fracture. Pitchstones may also contain phenocrysts, in which case it is a form of vitrophyre. Pitchstone has a resinous lustre, or silky in some cases, and a variable composition. Its colour may be mottled, streaked, or uniform brown, red, green, gray, or black. It is an extrusive rock that is very resistant to erosion.
पिचस्टोन (pitchstone) एक आग्नेय शैल है जो काले रंग की कांच जैसी होती है। यह ज्वालामुखी से निकले मैग्मा के तेजी से ठण्डा होने से बनती है।
