Meloidogyne chitwoodi populations from Tulelake, California; Ft. Hall, Idaho; Beryl, Utah; and Prosser, Washington, significantly (P < 0.05) reduced dry shoot weights of crested wheatgrass (Agropyron cristatum L., Gaertn. and A. desertorum, Fisch. ex Link, Schult.) cultivars Hycrest, Fairway, and Nordan in experiments conducted in a greenhouse and growth chamber. Shoot growth depression, root g...

Beryl (Be3Al2Si6O18) is a beryllium ring silicate that is composed of six-membered rings of [SiO4]4-tetrahedral and it crystallizes in the hexagonal crystal system with P6/mcc symmetry [1]. Of these, beryl variety a chromium-bearing variety of beryl, otherwise called as Emerald (Be3Al2Si6O18:Cr) contains vanadium, beryllium, iron, chromium. The refractive index, density and hardness of Emerald ...

Geochemistry and fluid inclusions studies were carried out on garnet and beryl from Quaternary alluvium deposits of Meluli-Namuhuca area, Mozambique. Garnet occurs as euhedral large crystals and is commonly brownish red, with a moderate brown hue in transmitted light. Apatite and ilmenite are the common inclusions. Geochemically, garnet is characterized by nearly homogenous chemical composition...

Mineralogical, geochemical and fluid inclusion studies reveal two favourable environments for the localisation of beryl mineralisations in the Precambrian rocks of Egypt: (1) emerald-schist; and (2) beryl-specialised granitoid associations. Emerald occurs within the mica schists and is typically confined to the Nugrus major shear zone. However, beryl associated with granitoids occurs in pegmati...

The Yamrang Pegmatite in the Ikhabu Field, Eastern Nepal is Nepal’s primary source of aquamarine. This paper reports detailed mineralogy and whole rock granite pegmatite geochemistry, major trace element data for alkali feldspar muscovite order to classify aquamarine-bearing Pegmatite, elucidate beryl-saturation processes evaluate potential geochemical exploration tools beryl-pegmatites. Five i...

The objective of this paper is to provide guidance for the design of the thick-walled cylinder made up of transversely isotropic material so that collapse of cylinder due to influence of internal and external pressure can be avoided. The concept of transition theory based on Lebesgue strain measure has been used to simplify the constitutive equations. Results have been analyzed theoretically an...

The Cuonadong deposit is the first large scale Sn-W-Be rare polymetallic located in southern Tibet, China, where beryl main beryllium-bearing mineral. In this paper, crystals pegmatitic and hydrothermal vein orebody from Xianglin area of are research objects, marked as Beryl-I Beryl-II, they investigated by EPMA, LA-ICP-MS situ micro-X-ray diffraction (XRD). Data EPMA reveal that beryls alkalin...
