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.

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。

磁海铁（钴）矿床颇具特色，以“石榴石-透辉石-磁铁矿”为基本矿石建造；成矿作用发生在早二叠世北山裂陷作用和火成活动晚期，以基性次火山岩浆期后富铁流体的（交代）充填为成矿方式，矿体产于辉绿岩体原生裂隙系统；成矿流体的化学演化具有典型（火山）岩浆期后热液演化特点，形成了一系列热液蚀变体，其中石榴石透辉石岩有别于传统理解的“夕卡岩”；成矿物质源于碱性玄武岩浆，基性次火山岩浆多次脉动式入侵是矿床形成的必要条件。文章较系统阐明了磁海矿床的成矿地质地球化学特征，证实了它的次火山热液成矿特征。

为确定辽宁青城子矿集区金、银的成矿时代，分别以含金硅化岩和含银网脉状石英晶体内流体包裹体为对象，应用Rb-Sr法测得金、银成矿的等时线年龄为（233±31）Ma～（234±14）Ma;作为对Rb-Sr法测年结果的验证，又以与贵金属矿石矿物共生的热液石英为对象，用40Ar/39Ar快中子活化法测得坪年龄tp=（238.78±0.74）Ma～（238.80±0.60）Ma，等时线年龄ti=（239.46±1.13）Ma～（240.35±0.88）Ma。Rb-Sr和40Ar/39Ar两种方法的测年结果基本一致，与本区印支期岩浆活动时代〔217.6Ma～（230.7±5）Ma〕吻合。
