The Tick Canyon Formation (Tt) or Tick Canyon strata, is an Early Miocene geologic formation in the Sierra Pelona Ridge of the San Gabriel Mountains in Los Angeles County, California.[2]
The Tick Canyon Basin drains into the Santa Clara River.[3]
Geology
[edit]The formation overlies the Oligocene to Lower Miocene Vasquez Formation, and underlies the Upper Miocene Mint Canyon Formation.[2][4]
The Tick Canyon strata was deposited on land mostly by streams and consists of green sandstones, coarse-grained conglomerates, and red claystones.[2][4][5] The Tick Canyon strata also contain abundant volcanic clasts, most of which resemble volcanic rocks of the Vasquez Formation.[6] It has an average thickness of 600 feet (180 m).[4]
North of the Tick Canyon Fault, the beds are almost vertical.[2]
Fossil content
[edit]It preserves vertebrate fossils of the Lower Miocene subperiod of the Miocene epoch, in the Neogene Period of the Cenozoic Era.[2][7]
