1982年笔者随新疆区调大队四分队在甜水海西南的喀喇昆仑山工作。我们在加勒万河谷,温泉,啌喀山口一带发现多处丰富的早二迭世筵类化石。这些筵类沿崆喀山口大断裂南北两侧作较有规律的分布。崆喀山口断裂北侧,为一套浅海相的灰岩,生物灰岩、角砾状灰岩夹灰黑色碳质粉砂岩及炭质细砂岩、浅黄绿色薄层细砂岩。角砾状灰岩及灰岩中含有大量筵类化石:Neoschwagerina sp.,Misellina sp.,Schwagerina sp.,Parafusulina sp.,Yangchienia sp.,Schubertella sp.,Pseudofusulina sp.,Ozawainellasp.,Chusenella sp.,Pseudodoliolina sp.,Sumatrina sp.等。
In 1982, I went with the unit of the 4th Brigade of Xinjiang Region in the Karakorum Mountains, southwest of the sea of sweet water. We found a number of rich Early Diego iterant feathered fossils in the Galleva Valley, Hot Springs, and Qiaqia Pass. These feast class along the Qiaqiakou large fault on both sides of north and south for a more regular distribution. On the north side of Qijiakoukou fault, it is a set of shallow marine limestone, bio-limestone and brecciated limestone with gray-black carbonaceous siltstone, carbonaceous fine sandstone and light yellowish green thin sandstone. A large number of feathered fossils are present in brecciated limestone and limestone: Neoschwagerina sp., Misellina sp., Schwagerina sp., Parafusulina sp., Yangchienia sp., Schubertella sp., Pseudofusulina sp., Ozawainellasp., Chusenella sp., Pseudodoliolina sp., Sumatrina sp.
