... He is probably most widely remembered for his studies of the geochemistry of magmatic hydrothermal wall-rock alteration in the Boulder County tungsten and gold district in Colorado and the East Tintic mining district in Utah. These studies have helped clarify the general processes of ore deposition and in a number of instances have provided direct guides to the occurrence of concealed ore deposits.

... separable periods of movement of magmatic hycirothermal fluids: First, an early district-wide flooding by neutral, magnesium-rich reducing solutions that dolomitized limestone wall-rocks and locally propylitized the basal parts of the earliest erupted lavas. Second, after a period of intrusion of minor bodies of monzonite and quartz-monzonite and the eruption of lavas, localized invasions of hot acidic solutions that severely leached and sanded the underlying limestones and hydrothermal dolomites, and strongly argillized the border areas of the minor intrusive plugs and the adjacent and nearby lavas.

... Fluid inclusions entrapped within these ore and gangue minerals indicate that they were deposited from near neutral, saline solutions at temperatures ranging from 150-300C. ~ 7 1~ ~ 1~ ~ 7 For Lovering the selection of the East Tintic mining clistrict for his most clefinitive studies of hycirothermal wallrock alteration was highly fortuitous, inasmuch as relatively few major mining districts elsewhere in the woric!
