Geochronological Study of the Jiashengpan Zn–Pb Deposit in Northern China: Implications for Base Metal Mineralization in Collisional Orogens

“…This area remained tectonically active from the late Paleozoic until the early Mesozoic. Carbonaceous to Triassic plutonic intrusions were widely developed through the Langshan-Zhaertai areas, with lithologies ranging from diorite to granite [17][18][19][20][21][22] (Figure 1). A series of east to west-trending thrust faults and shear zones were also developed in response to the tectonic activity ( Figure 1).…”

“…One school of thought, based mainly on the "arc-like" geochemical characteristics of Carboniferous-Permian intrusions, proposes that this activity resulted from the prolonged subduction of the Paleo-Asian Ocean (PAO) beneath the NCC, with the final enclosure of the ocean basin taking place at the end of the Permian to early Triassic [23][24][25]. In recent years, growing evidence from sedimentology, paleomagnetism, and paleontology show that the PAO was closed as early as the Devonian [26], and the late Paleozoic magmatic and tectonic events took place in a post-collisional extensional environment [21,27]. Marine sediments with Late Paleozoic ages are regarded to have formed in the shallow water environment of a small basin, rather than the PAO [28,29].…”
