金矿床成矿作用从矿带、矿床到矿体甚至矿脉均受到不同级别的构造变形控制。

In order to cut down the cost and pursue economy of scale, every enterprise chartered big vessels to transport a great deal of iron ore when ordering. However, the massive stock occurred because it far more overpast the demand of steel enterprises throughput. Next, the volumes stock bring on abundant cost of stockpile, since it can not be distributed in time due to limited capacity of transportation. Furthermore, there is a big pressure to railway authority to distribute the iron ore.

钢铁企业订购铁矿石时，为降低成本、追求规模效益，一般采取大船进行海运运输，而一次的运量可能大大超过了企业近期的生产能力，大量的库存便产生了；其次，如此大量的矿石集中到港，无法通过疏运能力的"瓶颈"，在港口堆场堆存又产生了大量的堆存费用；此外，大批量的疏运对铁路部门也产生了压力。

对含泥量高、渗透性差的矿石，添加渗滤物质以改善渗透性能进行了研究。

These two ores have contrasting mineral associations: anthothyllite + plagioclase + rutile + magnesiohornblende + alkline fledspar for red ore and anthothyllite + phlogopite + epsode + Rutile for black ore.

根据岩相学观察，认为红色金红石矿中存在如下方向的反应：镁角闪石+碱性长石→直闪石+／-斜长石+／-金云母，斜长石很可能只是过渡相，反应最终将形成直闪石+金云母。

This study was only focused on the No.Ⅰore body. Based on detailed logging and dating results, it is considered that mineralization of the Cu_Au porphyry occurred in Late Jurassic. The formation of the ore body is related to the Late Jurassic augen quartz phenocryst_bearing hornblende_quartz diorite porphyrite intrusion（J3δομ）.

通过对雄村铜金矿床Ⅰ号矿体详细的地质编录和测年成果，发现雄村斑岩型铜矿床形成于晚侏罗世，矿体的形成与晚侏罗世侵位的、含眼球状石英斑晶的闪长玢岩（J3δομ）有关，成矿岩体呈不规则的岩枝状，全岩矿化，岩体中Au的平均品位大于1g/t，Cu含量大于0.7 %。
