Abstract

The delicate methods of modern microscopical petrology have
added greatly to our knowledge of igneous rocks. Very
little work of this description has hitherto been attempted in
Tasmania, but the present studies, undertaken in connection
with the Launceston Microscopical Club, have been entered
upon in the hope of throwing additional light upon the
genesis and intimate structure of our eruptive rocks. It is
proposed to continue the descriptions from time to time as
materials and opportunity permit, and as they must at first
necessarily partake of the nature of preliminary work, remarks
upon their classification will be withheld till sufficient
progress has been made to justify generalisations. A glance
at the current literature of our science suffices to show that
the microscope in petrology is each year enlarging the
boundaries of its conquests, and it is hoped that the present
contributions will prove helpful to the stratigraphical
geologists of this island.
