TERUGGITE, 4CaO
WebThe early colemanite, meyerhofferite, ulexite and teruggite nodules were probably formed directly from brines penecontemporaneously within the unconsolidated sediments below the sediment/water interface, and continued to grow as the sediments were compacted. Later generations of colemanite occur in vugs, veins and as fibrous margins to ... WebFeb 9, 2024 · Close mobile search navigation. Article navigation. Volume 53, Number 11-12 chuck beck richfield mn
Teruggite Mineral Data
WebOccasionally, these powdery potato-shaped teruggite nodules contain very small spherulites of cahnite (Fig. 6). This is the first record of this type of teruggite and cahnite occurrence from borate deposits (Helvacl 1977). The crystal structure of teruggite from the Emet deposits was described by Negro et al. (1973). WebThe crystal of teruggite used in this investigation was a colorless prismatic fragment elongated along the c axis and about 0.04 x 0.07 x 0.23 mm in dimensions. The space group P21/a reported by Aristarain and Hurlbut (1968) was confinned. The cell parameters were redetermined and refined using the least-squares method applied to fifty high order WebTeruggite, Ca4Mg[B6As(OH)6O11]2(H2O)14, the only known boroarsenate of natural origin, has almost twice as much information per unit cell, with IG,total = 1201.992 bits/cell. The observed difference in structural complexity between I and teruggite is the consequence of their chemistry (hydration state) and different formation conditions. ... chuck beck cars
