引言在西澳伊尔加恩地块许多钙结岩中都已发现铀矿化及矿化点。铀在这些建造中以钒钾铀矿的形式产出(K_2(UO_2)_2V_2O_8,3H_2O)。许多作者评述过伊尔加恩地块的地貌和地质环境并提出成因模式。在此类矿床中,不深的潜水层在矿化形成过程中起主要作用。Mann和Deutscher(1978)着重描述潜水层在地块北部和伊利里邻近的Hinkler Well河道中的作用。从伊利里河道井水中取样能使我们详细评价水中物理-化学特征及矿化形成过程。地质、气候、水文情况伊利里钙结岩主要发育在占西澳西南四分之一的伊尔加恩地块上,它是澳洲大陆的主要地核,为冈瓦那地核之一。古老的太古代基底,以大混合岩带为主体,该带被沉积建造和绿岩
INTRODUCTION Uranium mineralization and mineralization have been found in many calcareous rocks in the Ilganer block in Western Australia. Uranium is produced in the form of vanadium potassium uranium deposits (K 2 (UO 2) 2V 2 O 8, 3H 2 O) in these constructions. Many authors have reviewed the geomorphology and geology of the Ilgan site and proposed a genetic model. In such deposits, the undeveloped submersion plays a major role in mineralization. Mann and Deutscher (1978) focussed on the role of the submerged layer in the northern Hinkler Well, adjacent to the Erieri site. Sampling well water from the Illy River channel allows us to evaluate in detail the physico-chemical characteristics of water and the formation of mineralization. Geology, Climatic and Hydrological Conditions Yili Li calcium karst is mainly developed on the Ilgaan block, which occupies one quarter of the southwest of Western Australia. It is one of the main cores of mainland Australia and one of the Gondwana. The ancient Archean base, with a large mixed rock belt as the main body, the belt was deposited and green rock deposition
