河南泌阳凹陷钾盐成矿地质条件分析

摘要

通过对泌阳凹陷地层层序、构造特征、沉积环境进行分析，总结了岩盐、天然碱、钾盐的成矿规律，探讨了钾盐成矿地质条件，认为泌阳凹陷具“高山深盆”的构造条件、干旱的气候环境、具多源性钾物质来源，具备盆地卤水钾盐成矿地质条件。%Through?the?analysis?of?the?stratigraphic?sequence,?tectonic?characteristics?and?sedimentary?environment?of?Biyang?sag,?the?paper?summarizes?the?metallogenic?regularity?of?rock?salt,?trona?and?potassium,?discusses?the?geological?conditions?of?potassium?ore-forming.?The?paper?argues?that?Biyang?sag?has?the?tectonic?conditions?of?“high?mountains,?deep?basin”?and?drought?climate?environment,?owns?sources?of?multiple-source?potassium?materials?and?possesses?the?geological?conditions?of?basin?brine?potassium?ore-forming.
