Tridymitic jasperoid deposits in N. W. Queensland
Mineralium Deposita, 1977A number of small, fault-controlled, siliceous, copper deposits in the Precambrian of North-West Queensland contain most of their silica as tridymitic jasperoid. The tridymite has pseudomorphically replaced the dynamic metamorphic assemblages that resulted from earlier fault movements.

Geology and geochemistry of jasperoids from the Gold Bar district, Nevada
Mineralium Deposita, 2006Gold Bar is one of several Carlin-type gold mining districts located in the Battle Mountain–Eureka trend, Nevada. It is composed of one main deposit, Gold Bar; five satellite deposits; and four resources that contain 1.6 Moz (50 t) of gold. All of the deposits and resources occur at the intersection of north-northwest- and northeast-trending high-angle

AbstractDetailed characterization was performed on the chalcedonies from the jasperoids of the Pietratonda–Poggio Peloso Sb–Au deposit (southern Tuscany, Italy). The main purpose was to retrieve information on the geothermal fluids that formed the chalcedonies and the source of antimony concentrations.

The origin of jasperoid in limestone
Economic Geology, 1962The name jasperoid has been applied to rocks that consist mainly of silica and that have formed by replacement. This paper considers only those jasperoids formed by replacement of limestone. Major problems involved in the origin of such jasperoid include: source of the silica; nature of solutions that dissolve, transport, and precipitate silica; and ...

Stable isotope investigation of gold-bearing jasperoid in the central Drum Mountains, Utah
Economic Geology, 1979The oxygen, hydrogen, carbon, and sulfur isotope relationships in gold-bearing jasperoid and associated carbonate and pyrite from the Drum Mountains, Utah, have been studied for the purpose of determining certain genetic relationships of these mineral occurrences.

Paragenesis of the Tri-State jasperoid [Missouri-Kansas-Oklahoma]
Economic Geology, 1951The characteristic gangue of the zinc ores of the Tri-State district and northern Arkansas, locally termed jasperoid, is believed by some geologists to be older than the sulphides and to have been extensively replaced by them. Others believe there has been no replacement of the jasperoid and that jasperoid and sulphides were deposited contemporaneously.
