Minerals from the Viburnum Trend and Tri-State Districts - Missouri. The minerals below are from the well-known mining districts in Missouri, the Viburnum Trend in the southeast part of the state, and the Tri-State district in the southwest part of the state. The Tri-State district has been closed for many years now, while the Viburnum Trend is. The Viburnum Trend lead-zinc mining subdistrict is located in the southeast Missouri portion of the Ozark Plateau. In and , we assessed the ecological effects of mining in several watersheds in the region. We included macroinvertebrate surveys, habitat assessments, and analysis of metals in sediment, pore water, and aquatic by:

Reflectance measurements and petrographic characteristics of organic particles define an alteration zone about 20 km wide, centered on the Viburnum Trend ore deposits. Within this zone, bitumen has been generated from kerogen. In contrast, no evidence of local bitumen generation was observed in samples located more than 10 km from the Viburnum by: ALTERATION OF ORGANIC MATTER IN THE VIBURNUM TREND LEAD-ZINC DISTRICT OF SOUTHEASTERN MISSOURI [Alan L., et al Henry] on Author: et al Henry, Alan L.

Francois Mountains, a region of Precambrian igneous rock exposed at the structural apex of. Southeastern Missouri Jeffrey L. Imes Introduction Lead-zinc mining in the Viburnum Trend (fig.
1) began in the mids around Viburnum, Missouri. During the next 2 decades, 10 mines were opened along the south-trending ore deposit. Generally, the older mines are located in the northern part of the trend, and newer mines are located in the southern part of the trend.
In response to declin ing. The Viburnum Trend of southeast Missouri is a world-class, Pb-Zn-Cu MVT district. Its sulfide ores are generally lead-dominant (Pb:Zn > 5) and occur mainly in the upper portion of the Upper Cambrian Bonneterre Dolomite, typically within and above the stromatolite reef-grainstone carbonate facies (Gerdemann and Myers, ) (Fig.
1A and B).Most ore mineralization is disseminated in dolomite Author: Kevin L. Shelton, B. Danielle Cavender, B. Danielle Cavender, Laura E. Perry, James D. Schiffbauer. The Viburnum Trend of southeast Missouri is one of the world’s largest producers of lead. The lead occurs as galena, predominantly in two crystallographic forms, octahedrons and cubes.
Many studies have shown that octahedral galena is paragentically early, the more abundant of the two crystal forms, and is commonly modified in the cube. Those studies also have shown that the cubic form is Author: Richard D.

Organic matter, herein referred to as bitumen, is commonly observed in the Mississippi Valley-type Pb-Zn deposits or the Viburnum Trend, southeast Missouri. In the mines, bitumen exudes from mine walls as a tacky liquid and occurs in vugs and openings as solid spherical blebs. In addition to solid.
The role of organic matter in Mississippi Valley-type Pb-Zn deposits has been studied by systematically sampling and characterizing various types of organic matter in the Upper Cambrian Bonneterre Formation in lead-zinc mines from the Viburnum Trend and from rocks as far as 20 km away from the Trend.
