Summary edit
DescriptionBioherm (Tin Mountain Limestone, Lower Mississippian; Funeral Mountains, Inyo County, California, USA) 2.jpg |
English: (looking ~east)
This is the southern Funeral Mountains in southeastern California. The bedrock succession in this region consists of Proterozoic to Mississippian marine sedimentary rocks, which are overlain by Cenozoic nonmarine sedimentary rocks. Seen here is the western face of a small ridge just southeast of Bat Mountain. The light-gray mass is a large mudmound in the Lower Mississippian Tin Mountain Limestone. Mudmounds of this age are often referred to as "Waulsortian mounds", the origins of which are somewhat mysterious. Waulsortian mounds do contain macroinvertebrate fossils, but they are principally composed of fine-grained calcareous sediments ("mud") and completely lack framework-building organisms such as corals. Coral reef environments were hit hard in the Late Devonian, not long before this, at the Frasnian-Famennian mass extinction. They may be microbial bioherms ("reefs"). The Tin Mountain Limestone itself consists principally of crinoidal limestones.
