Abstract

• The investigated area is situated in Hopang Township, “Wa” Self-Administered Division in northern Shan State, Myanmar. This area is mainly composed of various lithologic units ranging in age from Precambrian to Mesozoic. Precambrian units are mostly metasedimentary rocks and Paleozoic to Mesozoic units are carbonate and clastic sedimentary rocks. A number of known lead-zinc mines within the Shan Plateau lie in a broad NE-SW orientated belt extending from the Shan Scarp in the west up to the Chinese border in the east. Hopang area is economically important because the sizeable Pb-Zn-Cu mineral deposits are well developed at Hpalin mine. The carbonate-hosted PbZn-Cu veins are observed as fissure filling and cavity filling types occurred along the northeastsouthwest striking fault. The major ore minerals such as pyrite, chalcopyrite, sphalerite and galena are associated with the lesser amount of azurite, malachite, chalcocite, bornite, arsenopyrite, chrysocolla and laurionite. Limestone, dolomite and porphyritic biotite granite are mostly abundant and they are used for industrial materials, construction materials and decorative stone.
