The investigations show that the studied thrust-nappe structures began to form during the Devonian-Carboniferous periods,as a result of the southward Type A subduction zone is caused by collision of the Middle Kunlun Islands and the southern boundary of Tarim Block.

研究表明,铁克里克逆冲推覆构造是由于志留纪-泥盆纪古中昆仑岛弧与塔里木地体南缘的碰撞拼接作用,造成塔西南的南向A型俯冲,于泥盆纪-石炭纪开始发育形成的。

The strata in upper Sinian, late Proterozoic Eras and cambine system, Ordovician, Silurian ,early palaeozoic and Devonian ,late palaeozoic outcrop in In this area. The main strata are Sedimentary superficial metamorphic fine Clastic Rock with carbonate rocks .

区内主要出露有早古生代寒武系、奥陶系、志留系及晚古生代泥盆系,发育一套浅变质细碎屑岩与碳酸盐岩沉积建造。

Thepalaeozoic strata are very developed in Xaiza area. Xainza area is so ideal for studyDevonian and its fauna in north Tibet because of good outcropping, continuoussediments, simple structure, various categories fossiles of Devonian section.

申扎地区的古生代地层较为发育，泥盆系剖面出露良好、沉积连续、构造单一，古生物化石丰富，门类也较为齐全，是研究藏北地区泥盆系及其动物群的理想地区。
