The Kalaxianger porphyry copper deposit(belt)is located in a Late Paleozoic island arc on the southern margin of the Altay Mountains.

The direction of paleocurrent was found to be 230°-356° and the sediments were found to originate from the southeast Bikou island arc, which is close to the active continental.

the basalt is belong island arc tholeiite and series of the calc-alkaline,and have character of island arc in rare earth element and trace element.

The ore-bearing porphyry at island-arc in the Gongpoquan Copper Deposit:its geology and geochemistry;

The characteristics of the lithology,petrogeochemistry and microelements indicate that the volcanic rocks of Dahalajunshan Formation in this area should belong to the offspring of island-arc tectonic settings,instead of rift volcanic rocks.

The author considers that there are close relationships between the plane form of island-arcs and submarine ridges.
