“…Lanmuchang Hg-Tl-Au deposit in southwest China is the first reported independent Tl deposit in the world [31]. The additional small size of Carlin-type deposits are also found in Canada, the Republic of North Macedonia, Russia, Southern Tienshan Belt (including Uzbekistan, Tajikistan, Kyrgyzstan, and China), Indonesia, and Malaysia [6,30,[32][33][34]. Given the widespread distribution of the Carlin-type gold deposits, Tl mineralization areas associated with gold, antimony, and mercury are supposed to become the global important Tl ore deposit occurrences.…”

Secondary Sulfate Minerals from Thallium Mineralized Areas: Their Formation and Environmental Significance

Thallium is a highly toxic metal and is predominantly hosted by sulfides associated with low-temperature hydrothermal mineralization. Weathering and oxidation of sulfides generate acid drainage with a high concentration of thallium, posing a threat to surrounding environments. Thallium may also be incorporated into secondary sulfate minerals, which act as temporary storage for thallium. We present a state-of-the-art review on the formation mechanism of the secondary sulfate minerals from thallium mineralized areas and the varied roles these sulfate minerals play in Tl mobility. Up to 89 independent thallium minerals and four unnamed thallium minerals have been documented. These thallium minerals are dominated by Tl sulfosalts and limited to several sites. Occurrence, crystal chemistry, and Tl content of the secondary sulfate minerals indicate that Tl predominantly occurs as Tl(I) in K-bearing sulfate. Lanmuchangite acts as a transient source and sink of Tl for its water-soluble feature, whereas dorallcharite, Tl-voltaite, and Tl-jarosite act as the long term source and sink of Tl in the surface environments. Acid and/or ferric iron derived from the dissolution of sulfate minerals may increase the pyrite oxidation process and Tl release from Tl-bearing sulfides in the long term.

“…It should be noted, that the olistostrome for ma tions were not de scribed in de tail and not de picted on the de tailed geo log i cal maps of the area of the Kadamzhai and Khaidarkan de pos its. At the same time, the study of these for ma tions is of prac ti cal im por tance, since the ore-bear ing si lici fied rocks (the so-called "jasperoids") are con fined to the con tacts of lime stone bod ies (olistoliths in many cases) and terrigenous sed i ments (Vaulin, 2016;Nevolko et al, 2019).

As so ci ate ed i tor: Anna Wysocka A Late Car bon if er ous (Early Moscovian) olistostrome de vel oped in the Kadamzhai and Khaidarkan gold-an ti mony-mer cury de pos its on the Alay Ridge north ern slope (Kyrgyzstan), at the front of the Late Pa leo zoic South ern Tian Shan nappes, is char ac ter ized. It com prises a sub-nappe olistostrome in a collisional tec tonic set ting. The olistostrome con tains olistoliths and olistoplaques con tain ing parts of the mid-Pa leo zoic sed i men tary suc ces sions be long ing to the parautochthon and lower nappes of the north ern Bukantau-Kokshaal branch of the South ern Tian Shan nappe belt. The olistostrome ac cu mu lated ahead the ad vanc ing nappes in the foredeep ba sin that was filled with turbidities and de bris-flow de pos its (Tolubai Formathion). The parautochthon was partly dis mem bered into thrust lime stone sheets which dis in te grated and slid into uncon sol i dated sed i ments of the foredeep ba sin, form ing large lime stone olistoliths and olistoplaques. Olistoliths con tain ing shales and bed ded cherts were slid from the lower nappes. Tec tonic brec cias up to melange scale are pres ent in some olistoliths, sug gest ing tec tonic dis in te gra tion within the nappe pile and the sub se quent slid ing of the tectonized blocks into the olistostrome ba sin. Ore-bear ing si lici fied rocks (so-called "jasperoids") with an ti mony-mer cury and gold min er al iza tion are lo cated pre dom i nantly along the con tacts of the lime stone olistoliths/olistoplaques with a terrigenous ma trix.
