河南省晚古生代铝土矿、煤矿可能是一个统一的成矿系统

Late Paleozoic Bauxite and Coal Mines in Henan Province May Be a Unified Mineralization System

摘要: 河南省晚古生代铝土矿、煤矿在空间上共存，在时间演化上或者形成机制上是不是一体的？或者铝煤是否是在统一成矿系统完成的？针对这个问题，我们在新的整体化的流体(气体)地球科学观指导下，运用幔汁辐射理论对其进行分析研究后认为，① 河南省晚古生代铝土矿是热液矿床，成矿物质来源于地幔流体；② 河南省晚古生代的煤矿和夹矸的形成来自于碱交代热液，形成夹矸高纯度高岭石的物质是碱交代热液的末端组分；③ 河南省晚古生代煤的形成过程中深部碱交代活动非常强烈，在含煤地层中形成了大量的热液矿物；④ 河南省晚古生代铝土矿、煤矿的形成可能不是“外生沉积”而是“内生沉积”！即河南省晚古生代铝土矿和煤矿形成于一个完整的幔源烃碱流体成矿系统。

Abstract: Late Paleozoic bauxite and coal mines in Henan Province coexist spatially, but it remains unclear whether they are integrated in terms of temporal evolution or formation mechanisms, or whether the bauxite and coal were formed within a unified ore-forming system. To explore this question, we have conducted an analysis and study guided by a new holistic fluid (gas) geoscientific perspective and applying the mantle juice radiation theory. Our findings suggest that, first, the Late Paleozoic bauxite in Henan Province is hydrothermal in origin, with ore-forming materials sourced from mantle-derived fluids. Second, the formation of the Late Paleozoic coal and interbedded shale in Henan Province is attributed to alkaline metasomatic hydrothermal fluids, where the high-purity kaolinite in the interbedded shale represents the terminal components of these fluids. Third, the formation process of the Late Paleozoic coal in Henan Province is characterized by intense deep-seated alkaline metasomatic activity, resulting in the widespread formation of hydrothermal minerals within the coal-bearing strata. Finally, we propose that the formation of the Late Paleozoic bauxite and coal mines in Henan Province may not be “exogenic sedimentation” but rather “endogenic sedimentation,” suggesting that these mines were formed within a complete mantle-derived hydrocarbon-alkaline fluid ore-forming system.
