From the fields of regional crust-mantle structure, metallogentic settings, history of tectonic-magmatic activity, distribution of high antimony anomaly, characteristics of deposit, origin of ore-forming materials (including Sb, C, Si, S, solution and associated elements), black dikes, the relation of deposit and mantle metasomatism fluid is expounded by means of geology and geophysics. Xikuangshan antimony deposit is proved to be a typical vein deposit formed by mantle metasomatism fluid. On the basis of this knowledge, the prospecting criteria of blind orebody of the deposit are given as follows: extensive structuer which indicating the activities of mantle metasomatism fluid, change of host rocks (especially exsisting shale barrier bed), silication and carbonization alteration.

Whereas osteoporosis is unassociated with bone pain, osteomalacia has been associated with isolated or generalized bone pain.39,40 The cause is thought to be hydration of the demineralized gelatin matrix beneath the periosteum; the hydrated matrix pushes outward on the periosteum, causing throbbing, aching pain.7 Osteomalacia can often be diagnosed by using moderate force to press the thumb on the sternum or anterior tibia, which can elicit bone pain.7,40 One study showed that 93% of persons 10 to 65 years of age who were admitted to a hospital emergency department with muscle aches and bone pain and who had a wide ariety of diagnoses, including fibromyalgia, chronic fatigue syndrome, and depression, were deficient in itamin D.41
然而,骨质疏松症与骨痛无关联,而软骨病则与局部性或全身性骨痛有关。其原因被认为是骨膜下已去矿质化的胶原基质上发生的水合反应,水合的胶原基质在骨膜上向外扩张,引起阵痛。软骨病可通过以拇指适度挤压胸骨和胫骨前方以引起骨痛感。一项研究显示10岁到65岁中有93%的人向医院急诊室承认有肌肉疼痛和骨痛症状,他们还有一些其他症状包括纤维肌痛、慢性疲劳综合征、抑郁等,该研究显示他们都缺乏维生素D。本人已认领该文第9、10两部分,48小时后若未提交译文,请其他战友自由认领。本人已认领该文11、12部分编译,48小时后若未提交译文,请其他战友自由认领。本人认领第十三部分,48小时内交稿请战友纠错!
