江西省上饶县上村钒矿成矿作用及找矿远景分析
|
摘要
上村钒矿为江西有色地质勘查一队近年来探获的一中型以上钒多金属矿床,矿体分布在寒武系底—下统荷塘组底部石煤层中,受地层、岩性、岩相古地理控制明显。区内断层多为破矿构造,破坏了矿体的连续性。钒元素主要赋存于与炭质共生的含钒水云母、钒云母中,少数被粘土矿物、炭质所吸附。通过对上村钒矿的矿床地质特征、成矿作用及矿床成因模式的探讨和研究,总结出石煤型钒矿的成矿规律,并对矿区的找矿远景进行了分析,认为本矿区深部及外围大面积出露的寒武系底—下统荷塘组地层都具有良好的找矿远景,找矿潜力巨大。
The Shangcun vanadium mine is a medium-sized and above vanadium-polymetallic deposit discovered in recent years. The ore body is distributed in the bottom coal seam of the Cambrian Hetang Formation,which is obviously controlled by stratigraphic,lithologic and lithofacies palaeogeography. Most of the faults in the area are destructive structures,which destroy the continuity of the ore body. Vanadium mainly occurs in vanadium-bearing mica and vanadium mica coexisting with carbon,and a small amount is adsorbed by clay minerals and carbonaceous materials. Based on the discussion and study of the geological characteristics,metallogenesis and genetic model of Shangcun vanadium deposit,the metallogenic regularity of stone-coal type vanadium deposit is summarized,and the prospecting prospect of the deposit is analyzed. It is considered that the Lower-Lower Cambrian Hetang Formation strata exposed in deep and peripheral areas of the deposit have good prospecting prospect and great prospecting potential.
