Abstract:The Yueryagold deposit is located in the middle segment of north margin of the North
China is a large gold deposit in Jinchangyu-Yuerya mineralization concentration area and hosted
in granite body and its contact zone with strata of the Changcheng system in the Eastern Hebei Province.
Systematic investigations on geologic characteristics,fluid inclusions,oxygen and hydrogen isotopes,
sulfur and lead isotopes,trace element and rare earth elements,show that the ore-forming fluid has the
feature of low salinities and medium-high
