Through studying on contact zone shape,change of Fe and Cu grade,as well as the high accuracy magnetometer survey,thinks the zone to conform to the result of the magnetometer survey is the advantageous mineral zone.

This paper mainly deals with the types of ore-controlling structures and their space distribution,the features and occurrence of contact zone,the relations between the contact zone and metallization,as well as the emplacement mechanism of ore formation in Daye iron mine.

When the Tunneling Boring Machine (TBM) passing through the contact zones between slate and carbonate, engineering geological problems emerged.

Juma mineral water occurs in the contact zone of diorite porphyrite and skarn rock in theFutuyu copper mining area of Laiyuan County,Hebei Province.

In Yanshan time,the acid magma intruded into the middle part of marble,Shoushangou Formation,late Permian,Huadian area,that resulted in contact thermometamorphism and contact metasomatic metamorphism,and formed skarn Mo deposit in the exocontact of skarn,the orebody is in accordance with the strutigraphic occurrence.

The Qianping poly-metallic ore deposits mainly occur in NNE rifting belt of the internal contact zone of the“Qianping intrusions”and contain such major industrial mineral types as lead,zinc,copper,silver and iron.
