On the basis of 1∶1 000 000 remote sensing interpretation and local comprehensive interpretation, it is thought that the northeast part of Deerbugan deep fault might branch into two diverging faults near Alongshan of Inner Mongolia.

The new concept of the"Derbugan metallogenic province"is proposed instead of the"Derbugan metallo-genic belt".

There is a great potential of searchi ng for minerals in the northern part o f Heishantou within Derbugan metallogenic area(hereafter referred to as Northern Part).

Derbugan metallogenic province(northern part)falls into forest-marsh area,with a great potential of non-ferrous and precious metallic resou rces.

It was the deep fracture and palaeouplift developed before deposition of lower Xingouzui formation that visibly controlle.

In the deep fracture and feather fractoures to south occur several types of mineralized rocks.

The deep fracture within .

Within the basin of Shangdu,there may occured deep-large fault of long activiation which had affected the basin in its structure,lithofaces of the overlays,dynamic field of undergroud water and the environment of geochemistry.

There are two northwest-southeast deep-large faults in this area, the faults can be the migrat.

By research for deep faults and igneous rocks related to CO_2 gas fields, the author considers that magma is the carrier for CO_2 gas migration, while the development of igneous rocks is an important sign of the synchronous fault .

Heqin manganese depoit formed in an dissimilative trough environment superposed on successively descending platform during Camian-Norian of late Triassic, is closely related to the pull-apart basin induced by dextral strike slip of N-S trending deep fault zones in the western margin of Yangtz platform.

The potential source of hydrogen in sedimentary basin is from lower crust or mantle, and it can enter basin through deep fault that cut through the basement.
