WebIn ancient Roman times, this name was applied to several types of stone that would create sparks when struck against steel; Pliny the Elder described one of them as being brassy, almost certainly a reference to what we now call pyrite. [11] By Georgius Agricola 's time, c. 1550, the term had become a generic term for all of the sulfide minerals. Web[1] [2] The most common types include coal, lignite, oil shale, or black shale. [2] The organic material may be disseminated throughout the rock giving it a uniform dark color, and/or it may be present as discrete occurrences of tar, bitumen, asphalt, petroleum, coal or carbonaceous material.
WebThe Burgess Shale is a fossil -bearing deposit exposed in the Canadian Rockies of British Columbia, Canada. [2] [3] It is famous for the exceptional preservation of the soft parts of its fossils. At 508 million years old ( middle Cambrian ), [4] it is one of the earliest fossil beds containing soft-part imprints.

WebThe boundary is also known as the Bonarelli event because of 1-to-2-metre (3 ft 3 in to 6 ft 7 in) layer of thick, black shale that marks the boundary and was first studied by Guido Bonarelli in 1891.
