新疆博格达地区中—新生界碎屑成分自中侏罗世的中晚期开始发生了巨大变化,主要表现在:自中侏罗世晚期开始,沉积重矿物组合及相对含量发生较大变化,不稳定重矿物、较高级别变质岩岩屑明显增多,显示此时发生的物源属性变化及构造活动的存在;自侏罗系西山窑组沉积晚期开始,砂岩碎屑成分中的沉积岩碎屑明显增加,显示盆缘沉积岩物源的隆升和剥蚀作用。

首先,虽然有古地磁资料表明两地块从震旦纪到奥陶纪是逐渐靠拢并拼接在一起的,但华南地区至今没有找到证实这次碰撞结合的含有加里东洋壳残片在内的蛇绿岩混杂带,也没有发现与之有关的沟弧盆体系,对此有着不同的解释,这也是研究区多年来一直困扰许多地质学家的原因,也是大家一直争论的热点。

The time of the pedogenic process was in the last ice age, therefore this area was colder and drier in climate and lower in sea level than today. The main chemical process in the soil was oxidation, a period of the formation of oxide minerals such as limonite. With the deposition and covering of the marine facies layer in the postglacial period, the soil turned into diagenetic process. Consequently the chemical process in the soil was dominated by reduction and this process was the main development period for nodules of iron-manganese carbonate to form.
成土期处于末次冰期低海面、气候寒冷干燥期,土壤的化学过程是以氧化作用为主,是褐铁矿等氧化性矿物形成时期;冰后期海相层的沉积覆盖使土壤层进入成者阶段,土壤层的化学过程以还原作用为主,成岩过程是铁锰碳酸盆结核的主要生成期。

Orebodies occur in a fault near the axial region in the southern limb of the Jinjinghe-Hujiamiao inverted secondary anticline in the southern limb of the Hongyansi-Heishan composite syncline. Host rocks are dolomitic rocks in the middle and upper parts of the Devonian Qingshiya Formation. Their spatial distribution is obviously controlled by an interlayer fracture-fissure zone near the axial region in the steeply dipping southern limb of an anticline. Ores are dominantly of nodular and stockwork types and the feature of epigenetic mineralization is very pronounced.
