The discussion is divided into two parts (1) the Ozark region which includes the Tri-State district, Southeast Missouri lead belts, Northern Arkansas district, Central Missouri district and (2) the east-central region which includes the niinois-Kentucky fluorspar district, Upper Mississippi Valley Zn, Pb District, and central Tennessee Zn district. The reason for making this distinction is that the Ozark and east-central regions are differentiated on the basis of Pb isotope systematics (Goldhaber et al., 1995) and ore paragenesis (Hayes et al., 1997). These distinctions imply distinct or largely distinct fluid flow paths.

Currently in the United States, most of the lead produced comes from mines in Missouri, Alaska, Idaho, and Montana, primarily from lead-zinc and lead ores (361, 362). Worldwide, major lead deposits exist in association with zinc, silver, and/or copper (362). There are five major geological types of lead deposits volcanic-hosted massive sulfide deposits [Canada, Cyprus, Japan, Australia (Tasmania), Turkey] sediment-hosted deposits of sulfides interbedded with shales, and so on, formed in an anaerobic marine environment [Australia, Canada, Germany, United States (Alaska)] strata-bound carbonate deposits containing sulfide minerals [United States (Mississippi Valley), southern European Alps, Canada, Poland] sandstone-hosted deposits of finely crystalhne sulfides (Canada, France, Morocco, Sweden) and vein deposits of coarsely crystalline sulfide aggregates (western United States, Germany, Japan, Mexico, Peru) (364). The wide variety of compositions seen for lead minerals is illustrated by the representative lead minerals listed in Table XV (3,47). Below, we discuss the lead minerals that are most prevalent in nature in more detail.

A similar result is shown by the spatial distribution of EEEs induced by the 1811-1812 New Madrid, Missouri, earthquakes, mapped in Fig. 7. Indeed, the most relevant primary and secondary effects are located along the Mississippi Valley near New Madrid, consistently with the surface projection of the causative faults, and unquestionably provide diagnostic elements for assessing an epicentral intensity equal to XI (Guerrieri et al. 2011).
