Zircon SHRIMP Geochronology and Geochemistry of late Jurassic Volcanic Rocks in Huiyin Obo Area, Inner Mongolia, China

摘要

The primary object of this fundamental research is to reveal new study of Late Jurassic Manketou Obo Formation and Early Cretaceous Manitu Formation, Baiyingaolao Formation, in Huiyin Obo area, East Ujimqin County, Inner Mongolia. Several sets of experiments were carried out to test the validity of three formations’ age, and these forms can be contrasted with Chagannuoer Formation and Bulagehada Formation from “1/250000 Regional Geology Survey in Hesigewula Farm.” As a result of our study, we concluded that further research into the Mesozoic volcanic rocks on the Huiyin Obo is necessary.
