托盘沟地区上三迭统主要分布于吉林省汪清县天桥岭—托盘沟一带,是一套受轻微变质的中酸性火山岩及陆相碎屑沉积岩组成,有人认为属古生代,也有人认为属中生代。1963年,吉林省地质局第四地质队在天桥岭东南部马鹿沟黑色板岩中,曾采到Neocalami-tes、Pachypteris?等化石;后来又在复兴村南部一带采到Todites denticulata(Brongn.)Krasser、Taeniopteris cf.richthofeni(Schenk)Sze等化石,认为时代有属晚三迭世至早侏罗世的可能。1966年,第四地质队将该套地层命名托盘沟组,分上、下两段(下段为中性
The Upper Triassic area of the Toutaogou area is mainly distributed in the vicinity of the Tianqiao Ridge - Tundanggou of Wangqing County, Jilin Province. It is a moderately acidic volcanic rock and terrigenous clastic sedimentary rock. Some people think it belongs to the Paleozoic, while others consider the Mesozoic. In 1963, the fourth geologic team of Jilin Geological Bureau collected fossils of Neocalami-tes and Pachypteris? From the black deer in the red deer in the southeastern part of Tianqiao Ridge and later collected Todites denticulata (Brongn. ) Krasser, Taeniopteris cf.richthofeni (Schenk) Sze and other fossils, that the era belongs to the late Triassic to Early Jurassic may. In 1966, the fourth geological team named the set of stratums as a set of ditches, dividing into upper and lower sections (the lower section is neutral
