金顶及其外围新发现的白秧坪矿床令人关注，它们产在兰坪中新生代陆相碎屑沉积盆地内，这易使人把它们与以沉积岩为主岩铅锌矿床对比。但盆地处在大陆地壳强烈运动背景下，能够有效沟通下地壳和上地幔，矿体受构造控制，没有同生沉积成矿事实，也许代表了以沉积岩为主岩铅锌矿床新类型．大规模成矿主阶段流体的惰性气体同位素组成及演化显示成矿流体中混有2%～32%的地幔He（3He/4=He：0.19～1.97Ra），50.1%的地慢Ne（20Ne/22Ne=10.45～10.83，Ne/22Ne/22Ne=0.03）以及显著的地幔xe（129Xe/130xe=5.84～6.86，”。Xe/130Xe：2.26～2.71），地慢流体具有重要成矿意义。Re-0s法和。”Ar-州Ar法测定成矿时代是67-，-60Ma，晚于矿化主岩，与喜马拉雅期幔源和壳幔源碱性岩浆活动开始的时间一致。地慢流体或随岩浆活动或沿穿壳断裂系统上至地壳并与大气成因盆地卤水混合是：赶规模成矿基本方式。

Both the Jinding and Baiyangping ore deposits developed in the Lanping basin, which is a Mesozoic-Cenozoic terrestrial clastic sedimentary basin. Their occurrences can easily lead many people to compare them with the Pb-Zn deposit hosted in sedimentary rocks, such as Mississippian Valley-, Sedex- and sandstone-type Pb-Zn deposits. However, the Lanping basin developed in the settings of strong tectonic activity of the continental crust, which could cause an effective material exchange between the lower crust and the upper mantle. The orebodies are clearly tectonically controlled without syngenetic features, which probably represents a new type of the sedimentary rock-hosted Pb-Zn deposit. The isotopic compositions of noble gases in ore-forming fluids indicate that 2%-32% of helium (3He/4He=0.19 Ra-1.97 Ra) is derived from the mantle, 50.1% of neon (20Ne/22Ne=10.45-10.83; 21Ne/22Ne=0.03) from the mantle, and considerable amount of xenon (129Xe/130Xe=5.84-6.86; 134Xe/130Xe=2.26-2.71) from the mantle, which show that mantle fluids played an important role in the ore formation. The ore-forming age of 67-60 Ma obtained by Re-Os and 40Ar-39Ar dating methods is later than the host rock, which is coeval with the Himalayan alkali magmatism of the mantle source and mantle-crust source. In this paper, the mineralization of the Jinding and Baiyangping ore deposits is considered to be related to the mantle fluids which move upward with the magma or along the deep faults, and mix with the meteoritic brine in the crust to result in large-scale deposition.

There are giant mineral deposits, including the Jinding Zn-Pb and Baiyangping Ag-Co-Cu, and other important mineral deposits (e.g., Baiyangchang Ag-Cu, Jinman Cu deposits, etc.) in the Lanping Mesozoic-Cenozoic Basin, Yunnan Province, China. The tabular ore-bodies and some veins hosted in terrestrial clastic rocks of the Mesozoic- Cenozoic age and no outcropping of igneous rocks in the giant deposits lead to the proposal of syngenetic origin, but the giant mineral deposits are not stratabound (e.g. MVT, Sandstone- and Sedex-type). They formed in a continental red basin with intense crust movement. The mineralization is controlled by structures and lithology and occurs in different strata, and no sedimentary nature and no exhalative sediments are identified in the deposits. The deposits show some relations with organic matter (now asphalt and petroleum) and evaporates (gypsum). The middle-low-temperature (mainly 110℃ to 280℃) mineralization took place at a depth of about 0.9 km to 3.1 km during the early Himalayan (58 to 67 Ma). The salinity of ore-forming fluids is surprisingly low (1.6% to 18.0% wt NaCl equ.). Affected by the collision of the Indian and Eurasian plates, the mantle is disturbed under the Lanping Basin. The large-scale mineralization is closely linked with the geodynamics of the crust movement, the mantle and mantle-flux upwelling and igneous activity. Giant mineral deposits and their geodynamic setting are unique in the Lanping Basin.
