栖霞市西陡崖矿床地质特征及找矿方向

Geological Characteristics and Exploration Direction of Xidouya Deposit in Qixia City of Shandong Province

摘要:

西陡崖金矿为台前—陡崖成矿带上又一新发现的金矿床，该金矿受台前—陡崖断裂带严格控制，矿体呈脉状、透镜状；矿床平均品位3.96×10-6，平均厚度1.67m；围岩蚀变主要有黄铁绢英岩化，矿石中金属矿物主要为银金矿、自然金，黄铁矿等，矿床属岩浆期后中低温热液交代破碎蚀变岩型矿床。通过分析研究，西陡崖金矿在深部及外围找矿前景较大。

Abstract:

Xidouya gold deposit is another newly discovered gold deposit in Taiqian-Douya ore-forming belt. This gold deposit is strictly controlled by Taiqian-Douya fault belt. Its ore bodies are vein type and lenticular type. The average grade of this deposit is 3.96×10-6 , and the average thickness is 1.67m. Its alterations of country rocks are mainly pyrite phyllic alteration, and ore minerals are mainly silver metallic gold, native gold and pyrite etc., This deposit is low-temperature hydrothermal alteration type deposit formed after the magmatic stage. Through analysis and study, there is a large ore prospecting future in deep part and arounding areas of Xidouya gold deposit.
