Kyanite, sillimanite and andalusite in Georgia


, : Kyanite, sillimanite and andalusite in Georgia. Georgia Mineral Newsletter 13(1): 9-21

Detailed mineralogical descriptions of kyanite, sillimanite, and andalusite are given separately, together with geologic and geographic occurrences. Kyanite deposits occur in Habersham, Rabun, Talbot, Upson, Dawson, Fulton, Cobb, Fannin, Pickens, Cherokee, Lincoln, Banks, and Wilkes counties and generally occur in medium grade metasediments or as residual crystals and nodules derived from the weathering of sillimanite-biotite schists. The andalusite occurs as nodules and porphyroblasts from migmatized schists.

Minimally invasive cardiac surgery (MICS) through a small intercostal thoracotomy has many advantages, but it is still challenging because of limited mobility through the small skin incision and surgical field. The benefits of MICS should be reach...

The paper is concerned with the isolation of the native histone complexes: dimer (H2A-H2B), tetramer (H3-H4)2 and octamer (H3-H4-H2A-H2B)2 from the calf thymus chromatin under soft conditions (hydroxyl apatite) fractionation with the subsequent ge...

Hyperactivity of the hypothalamus-pituitary-adrenal axis is more common in elderly depression than in younger cohorts and glucocorticoids are known to influence serotonergic systems. The current study explores the interaction of glucocorticoids wi...

We examined the expression level of the midkine (MK) and c-erbB-2 genes in both tumorous and matched nontumorous specimens from 18 patients with breast cancer. Expression of the MK and c-erbB-2 genes in nontumorous regions was relatively low, and...

The average cost of weed control by means of 3 hoeings + 1 cultivation on 13 sugar cane estates over 4 years is given and is compared with the cost of 2, 4-D or MCPA + 3 cultivations between the rows. The latter was shown to be economic.
