Explor. 63, 37–56] has been shown to have applications in the McArthur Basin for defining the favourable stratigraphic unit hosting stratiform Zn–Pb–Ag mineralisation. A modified alteration index (AI Mark 3) has also been developed which eliminates the effect of the shale/dolomite ratio on the index and thus highlights the control of ...

The papers included in this volume were originally presented orally or as posters at the Society of Economic Geologists International Field Conference on Carbonate-Hosted Lead-Zinc Deposits, held in St. Louis, Missouri, June 3-6, 1995. The concept for this conference was first aired at the conclusion of an SEG field trip to the East Tennessee MVT district …
Hydrothermal Dolomite-Hosted Deposits: Host Rock: Dominantly hosted in dolomite. Minerals: Ore minerals such as sphalerite and galena are associated with dolomite replacement. Distribution: Occur in regions where dolomitization has taken place, often associated with hydrothermal fluid flow. Carbonate-Hosted Lead-Zinc (CHZ) …

Sediment-hosted Pb-Zn deposits can be divided into two major subtypes. The first subtype is clastic-dominated lead-zinc (CD Pb-Zn) ores, which are hosted in shale, sandstone, siltstone, or mixed clastic rocks, or occur as carbonate replacement, within a CD sedimentary rock sequence. This subtype includes deposits that have been …

Sediment-hosted Pb-Zn deposits contain the world's greatest lead and zinc resources and dominate worldproduction of these metals. They are a diverse group of ore deposits hosted by a wide variety of carbonate andsiliciclastic rocks that have no obvious genetic …
Although carbonate rocks are important for carbonate-hosted Pb Zn deposits, there is no effective constraint on the role of carbonate rocks during the Pb Zn mineralization process. This paper uses the giant Huize Pb Zn deposit (>7 Mt. metals @ 25–35 % Pb + Zn) as a case study and employs zinc isotopes to gain new insights into …
This report provides information on sediment-hosted zinc-lead mineral deposits based on the geologic settings that are observed on regional geologic maps. The foundation of mineral-deposit models is information about known deposits. The purpose of this publication is to make this kind of information available in digital form for sediment …
This report contains a global compilation of the mineral resource data for sediment-hosted lead-zinc (SH Pb-Zn) deposits. Sediment-hosted lead-zinc deposits are historically the most significant sources of lead and zinc, and are mined throughout the world. The most important SH Pb-Zn deposits are hosted in clastic-dominated …

The principal geologic and geochemical characteristics of the main classes of sediment-hosted zinc-lead(-silver-barite) deposits (SEDEX, Mississippi Valley-type, and Irish-type) are summarized with emphasis on the similarities and differences among them. Data that constrain sources of fluids, metals, and sulfur in the deposits and proposed ore genesis …
Sediment-hosted mineral deposits are the largest global resource of lead and zinc (Goodfellow et al., 1993;Mudd et al., 2017), base metals important to the energy transition (IEA, 2021).
Zinc–lead–barite deposits located in Lefan and Lower Banik localities of about 25km northeast of Zakho City, Northern Iraq consist of a group of strata-bound sulfides hosted in Upper ...

The southwestern Yangtze Craton zinc–lead province in Southwest China (Fig. 1 a) contains more than four hundred carbonate-hosted zinc–lead deposits with various sizes, and contributes over 26 million metric tons of zinc and lead resources for China (Liu and Lin, 1999).The zinc–lead deposits are mostly hosted in the Late …
The SYG (Sichuan–Yunnan–Guizhou) Pb–Zn mineral province in southwestern (SW) China has about 400 carbonate-hosted lead–zinc deposits, hosting over 200 million tonnes (Mt) Pb–Zn ores at 10 wt% Zn and 5 wt% Pb (Zhou et al. 2015). Previous works suggested that these deposits have MVT affinities in terms of their host …
Sediment-hosted ore deposits are the main source of lead and zinc, representing more than 50% of the world production and more than 60% of the reserves of these metals (see Wellmer et al., this Vol.).
