problem elephants. Physiological studies showed that stress was minimal to the other
elephants if no other animals were nearby, although elephants moved away from the area.
However, one hunter wounded an elephant and when his professional hunter tried to stop the
elephant; he was killed in the charge. Separately, in here is also a story of a car being
overturned with a family inside and them having to run for their lives. The father, carrying a
toddler, drew the elephant away from his family and then dropped the child behind a bush as
the elephant chased him and eventually caught up with him and killed him. In the Beeld
newspaper a couple of years ago there were pictures of one of the elephants rolling a car.
Rustenburg and the Bushveld Igneous complex is an unusual geological complex with multiple
stone types and seams from ancient volcanic activity. Igneous refers to that the rocks are from
lava or magma activity in contrast with sedimentary which is from formation in relation to
water and metamorphic which is related to rocks, including sedimentary rocks, altered by the
elements like heat and pressure forming rocks like marble, slate, gneiss, schist, micas,
feldspar, and quartzite. Igneous rock is divided into whether it forms underground (intrusive
plutonic) or from extrusive outpouring of lava. This forms the basis for the classification of
igneous rocks, including by the silica content. The latter determines how easily the molten rock
flows, so higher silica content flows are more treacle like and form islands like Hawaii
whereas low silica content rocks flow more easily and thinly like the komatiites rocks of the
Barberton Greenstone Complex. Hence high SiO2 content rocks (>63% are felsic and either
granite (intrusive coarse grained) or rhyolite (extrusive fine grained); intermediate (52% to
63%, intrusive diorite or extrusive andesite); mafic (42% to 52%, high iron content, intrusive
gabbro or extrusive basalt); and ultramafic (<45%, intrusive peridotite, extrusive komatiites).
The linear east-west mountains of the Magaliesberg slipped into view just north of the
brown hazy city of Pretoria, the former capital of the Afrikaner Transvaal.
