2063804
location:
Bor Pit, Dal'negorsk, Primorskiy Kray, Russia
description: The Bor Pit in Dalnegorsk, Primorskiy Kray, Russia, is a massive skarn deposit formed by hydrothermal activity associated with Cretaceous intrusive magmatism reacting with surrounding limestone and volcanics. Operated as an open-pit boron mine, this locality is world famous among mineral collectors for yielding stunning cabinet specimens, particularly of datolite. The datolite found here develops in diverse habits ranging from dense botryoidal crusts to sharp, translucent crystals in striking shades of green, yellow, brown, and white, frequently accompanied by calcite, hedenbergite, and quartz.
Pale yellowish green mostly gemmy and lustrous crystals of datolite measuring to 3.0 cm in size across the top of a massive datolite matrix. This is in very good condition and quite choice for the species. From the mid to early 1990s. The specimen comes with a previous label from the collection of Ray DeMark.
