一、鞍山式铁矿床一般水文地質特征产在前震旦紀的含鉄石英岩的所謂「鞍山式鉄矿」床,就水文地質观点来說,都屬於埋藏在坚硬的岩石中裂隙类型的矿床。矿体(前震旦紀鞍山统含鉄石英岩)以及它的圍岩(前震旦紀及震旦紀的变質岩系,各种火成岩)在經受各期地壳变动中,形成程度不同的裂隙系統。含鉄石英岩是这类矿床主要的含水層。該層構造裂隙,層面裂隙较为發育,受到構造影响很大,渗透
I. GENERAL HYDROGEOLOGICAL CHARACTERISTICS OF THE ANSHAN IRON ORE DEPOSIT The so-called “Anshan-type ores” beds containing 鉄-quartzite rocks in the Pre-Sinian are hydrologically geologically based deposits of fissures buried in hard rocks. The ore body (Pre-Sinian Anshan-hosted coniferous quartzite) and its surrounding rock (Pre-Sinian and Sinian metamorphic rocks, various igneous rocks) undergo different degrees of crustal deformation during the various crustal changes. Containing 鉄 quartzite is the main aquifer in this type of deposit. The layer structure fissures, fractures are more developed, affected by the structure of a great infiltration
