Sir
James Hall
(
January 17
,
1761
-
June 23
,
1832
) was a
geologist
and
geophysicist
, born in
Dunglass
,
Scotland
. He assumed the
Baronetcy
from his father in
1776
. Hall studied at
Cambridge University
and the
University of Edinburgh
. Hall was associated with other geologists of his period, particularly
James Hutton
and
John Playfair
. He carried out experimental research in geology to discover the nature of molten rock and the changes it made intruding into existing strata. He experimentally made several types of rock in his laboratory. His experimental heating and cooling of rocks helped his friend Hutton substantiate his
Plutonist Theory
, regarding the volcanic origins of rocks. His work showed that water (
Neptunist Theory
) was not the only cause of surface geological formations. Hall traveled extensively in
Europe
to examine geological formations of the
Alps
and
Mount Etna
. He noted the similarity of
lava flows
in
Italy
to locations in Scotland. James Hall died in
Edinburgh
, Scotland. His son,
Basil Hall
, was a noted traveler and writer.
