Strong evidence of epithermal/mesothermal mineralisation and alteration in the Kwaiahia region was noted with float rocks showing features such as fine-grained chalcedonic quartz + grey fine sulphides (mainly pyrite) with silvery grey to black minerals (stibnite), weakly banded chalcedonic quartz/ calcite and vuggy and lattice textures (bladed ...
Worldwide, bottlenose dolphins are found in the temperate and tropical parts where the temperature is between 10 to 32 C. They are found in parts of Japan, Australia, California, Chile, Hawaiian Islands, Norway, South Africa, Indonesia, Gulf of Mexico and the tropical and sub-tropical waters of the western pacific.
The other three species -- the striped dolphin, pantropical spotted dolphin and Atlantic spotted dolphin -- are named for their distinctive body markings. A Touch of White Five of the six dolphin species in genus Lagenorhynchus occur in the Atlantic Ocean, where they inhabit polar to temperate waters. Often called white-sided dolphins, species of this genus have a defining short beak. The white-beaked dolphin, the largest species, is found in subpolar waters in the northern Atlantic. The Atlantic white-sided dolphin also inhabits the northern Atlantic Ocean but in temperate waters. Also in this genus are dusky dolphins, named for their dark backs. They are found along the Atlantic coast of South Africa and around the Falkland Islands of South America, where their range overlaps with that of Peale's dolphins, another Lagenorhynchus species.
