Geological and Geochemical Characteristics of the Magma Conduit-Type Orebodies of Jinchuan Cu-Ni Sulfide Deposit

圆马蹄形锥体与长马蹄形锥体受控于裂隙形岩浆通道，圆形锥的岩浆通道是管状。

The circular and long horseshoe cones were controlled by crack-shaped magma channels while circular cones were associated with tupe-like magma paths .

中基性岩（500~1000Ωm）包括辉长岩相和闪长岩相呈漏斗状分布于辉石岩相外围，漏斗状形态预示岩浆上升通道可能在矿区西南部。

Basic rock mass including gabbro and diorite facies ( 500 ~ 1000 Ω· m ) displays a funnel shape and is distributed around the pyroxenite facies , and indicates a magma passage occurring in WS of the deposit area .

介绍了同忻井田煌斑岩的岩性及产状、时代，分析了岩浆上升通道，研究了煌斑岩侵入特征及其对煤层、煤质的影响。

It is introduced that the lithologic features and occurrence and intrusive geologic age of lamprophyre in Tongxin mine field , and analyzed the magma intrusive passage , and studied lamprophyre intrusive features and its influence on coal seams and coal quality .

无论它是深部断裂还是岩浆作用的通道，都说明它与幔源物质有直接的联系，它在成矿作用中起了重要的作用。

Whether it is a deep fault or the channel of magmatism , All this shows that it has a direct link with mantle materials , it played an important role during the mineralization period .

具有气泡超压聚集和气体通过可渗透性岩浆损失的火山通道内岩浆流体的动力学

Dynamics of magma flow inside volcanic conduits with bubble overpressure buildup and gas loss through permeable magma

4火山通道中充填的火成岩可以形成有效的裂缝系统而成为气体从岩浆房上移的通道。

Fissure systems can be developed in igneous rock of volcanic conduit , so it can become the channel for moving up of CO_ ( 2 ) gas .
