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.[1]
The Tick Canyon Basin drains into the Santa Clara River.[2]
The formation overlies the Oligocene to Lower Miocene Vasquez Formation, and underlies the Upper Miocene Mint Canyon Formation.[1]
The Tick Canyon strata was deposited on land mostly by streams and consists of green sandstones, coarse-grained conglomerates, and red claystones.[1] [3] [4] The Tick Canyon strata also contain abundant volcanic clasts, most of which resemble volcanic rocks of the Vasquez Formation.[5] It has an average thickness of 600feet.[3]
North of the Tick Canyon Fault, the beds are almost vertical.[1]
It preserves vertebrate fossils of the Lower Miocene subperiod of the Miocene epoch, in the Neogene Period of the Cenozoic Era.[1] [6]
