BARITE IN GEORGIA

Bedded Barite in the Geologic Record

Barite occurs throughout tlie gcologic ~.ecortl as massive beds, laminations, rosettes, and nodules. The niost importan( scientific and econo~iiic occurrences of barite are stratabound and stratifor~n massive betis from the Early Arcliean and tlie Early to Middle Paleozoic. Paleozoic beddecl barites are by far thc most volu~netricellp significant deposits in tlie geologic record. Additional occ...

Control of Barite Morphology by Double-Hydrophilic Block Copolymers

Barite particles with a rich variety of well-defined morphologies have been synthesized by using double-hydrophilic block copolymers (which consist of a hydrophilic solvating block and a hydrophilic binding block) as crystal growth modifiers to direct the controlled precipitation of barium sulfate from aqueous solution. The influences of variation in functional group and molecular structure of ...

Forecasting Tornadoes in Georgia

Some climatological data on the seasonal, diurnal, and geographical distribut>iorl of tornadoes in Georgia are presented, and the tornado "season" is defined as occurring from February through April. Twelve different storms producing t,ornadoes during one or more 12-hour forecast periods are studied for synoptic similarities. A mean tornado sounding and a 700-mb. composite chart, taken from dat...
