Mineralization is hosted by a complex assemblage of hydrothermally altered (argillic and sericitic) and unaltered porphyritic syenite-monzodiorite, intruding into lesser amounts of Nicola Group volcano-sedimentary rocks.
This ascending ore-forming fluid mixed with abundant meteoric water and caused the porphyry and wall rocks to become strongly sericitic and silicification.
Glazes of a jade green tone (also called plum green, or kingfisher green) were a feature of the Longquan kilns, which appear to have used a glaze mixture of a sericitic porcelain stone with some red clay.
Sericitic, argillic (advanced, intermediate and weak), silicic, chloritic, propyltic, zeolitic and alunite alteration zones have been recognized along this axis.
In these rocks occurring different alteration processes such as serpentine, epidotite, siliceous, sericitic, zeolite, chlorite, carbonate, and iron oxides.
The strata of the Xinghongpu Formation are divided into three different lithological sections as follows: the first section of the Xinghongpu Formation includes arenaceous phyllite; the second section of the Xinghongpu Formation is comprised of carbon-bearing phyllite and sericitic phyllite; the third section is mainly composed of banded lamellar limestone and calcitic-sericitic-phyllite.
The mineralization consists of vuggy quartz veins and breccias in granite with strong sericitic and local tourmaline alteration.
Subsequent hydrothermal carbonate alteration imparts additional variability and creates a range of sericitic schistose rocks containing varying abundances of carbonate, chlorite and pyrite, and producing a wide array of weathering colours.
The porphyry stocks consist of 2-ram to 5-mm quartz, feldspar and biotite phenocrysts in quartz and orthoclase, overprinted by strong sericitic alteration.
The main rock types are slates, quartzites, conglomerates, and sericitic and chloritic phyllites and schist, with some interbedded calc-silicate rocks (Martin-Izard et al., 2002).
