Abstract
Yishijlike ore belt is an important Gold Copper metallogenetic belt in Western Tianshan metallogenetic zone.The gold deposit types are mainly divided into two types:magma hydrothermal and volcanic hydrothermal type.The first type has a genetic relationship with hypabyssal and super hypabyssal intrusives.The later is associated with volcanic hydrothermal activities in lower carboniferous system with the orebody occurring in Dahalajunshan group volcanic horizon.Two types of gold ore deposits are strictly controlled by tectonic structures,volcanic strata and granite rocks (veins).
