中国川滇黔寒武系磷矿床地质特征、成矿规律与找矿方向
Geological characteristics,metallogenic regularities and prospecting directions of Cambrian phosphate deposits in Sichuan-Yunnan-Guizhou region of China
摘要
Abstract
Phosphorus is an essential element for life and a critical mineral resource supporting agriculture and the new energy battery industry.The Ediacaran-Cambrian boundary represents one of the globally significant phospho-genic episodes,during which extensive phosphorite deposits formed in the Sichuan-Yunnan-Guizhou region,es-tablishing a major phosphorus resource base in southern China.This study compiles existing data and conducts field investigations on representative deposits to preliminarily summarize the geological characteristics,distribu-tion patterns,and ore-controlling factors of Cambrian phosphorite deposits in the Sichuan-Yunnan-Guizhou re-gion.It concludes that depression zones in intertidal flats,characterized by weak hydrodynamic conditions,favor the formation of thick but relatively low-grade phosphorus deposits with laminated and banded structures.In con-trast,intertidal shoal zones with stronger hydrodynamic conditions facilitate physical reworking of primary sedi-mentary phosphorite,creating favorable settings for high-grade deposits.These commonly exhibit sedimentary structures such as tabular cross-bedding,Wedge-shaped cross-bedding,and wavy bedding.Variations in the scale and grade of phosphorite deposits across different areas of Sichuan,Yunnan,and Guizhou during the Cambrian are primarily attributed to differences in lithofacies paleogeography,hydrodynamic conditions,and weathering and leaching processes.Based on the metallogenic regularities and controlling factors,recommendations for prospect-ing work are proposed.关键词
