ABSTRACT
This paper is the first paper, which discusses the geological research history work in
the Republic of Yemen during the period from 1852 to 1946. The geological research
work history in the Republic of Yemen is a brief rich culture history, included
information about the first and most famous Geologists.
INTRODUCTION
It is known that rich culture history is largely depended upon written documents,
whereas the geological research history work story must be inferred from the careful
study.
Based on variably detailed information of hundreds publications references. I decided
to divided the geological research history work in Yemen to four stages:
First Stage: 1852-1901
Second Stage: 1902-1946
Third Stage: 1947-1967
Forth stage: 1968 - until today
First Stage: 1852-1901
In my opinion this First Stage must started from the middle part of the ninetieth
century to the early part of the twentieth century.
For this first stage I gave it two new names:
First name: The First Systematic Geological Observation Stage.
Second name: Carter's Stage.
Carter, H.J., 1852
He was interested in Yemen and especially in the southern part of the Arabian
Peninsula Coast. He was the first man and the lonely man of this stage (1852-1901).
He made the First Systematic Geological Observation in the region at variety of
selected locations along the southern Arabian Coast between Muscat and Aden.

2. Second Stage: 1902-1946
This Stage must started from the early part of the twentieth century until after World
War II. This Second Stage I called it: The Hinterland Studies Stage.
It is known, that the first geological studies of the hinterland of Yemen did not begin,
however, until the early part of the twentieth century.
The men of this stage were:
1- Raisin, C.A., 1902
He wrote notes on the Geology of Perim Island.
2- Kossmat, F., 1907
He made The First Systematic Geological Investigation of Socotra archipelago.
3,4- Crick, G.C., and Newton, R.B., 1908 Published determinations of Jurassic
mollusks.
5- Lloyd, R.E., 1910
In 1910, Lloyd, R.E., published observations on the sedimentary and volcanic rocks
from the area between Aden and Ad-Dali (some 110 km to the north).
6,7- Tipper, G.H., Vradenberg, E.W., 1910
In the same year Tipper, G.H., Vradenberg, E.W., respectively publishing
paleontological and petrologic determinations of Lloyd's sample collection.
8- Botez, G., 1912
In the sector between Hodaida on the Red Sea and San'a, Botez, G., carried out
hydrogeological studies.
9- Lamare, P., 1923
Investigated the southwestern and central parts of (former North Yemen). He
published the First Lithostratigraphic Accounts of the sedimentary successions of
Yemen.
10-Roman, O. (Rotman), 1923
Carried out petrologic studies on the samples, that Botez, G., had collected.
11- Little, O.H., 1925
Carried out a through geological reconnaissance of the Mukalla hinterland in the
coastal and plateau region of (former South Yemen) at that time, the Aden
Protectorate.
12,13- Rathjens, C., Von Wissmann, H., 1929,1934
More regional geographical /geological/ cartographic investigations were carried out
in various sectors of the interior of Yemen.
14- Basse, E., 1930
He made a specific reference to the western part (the high plateau) augmented by
paleontological determinations.
15- Carpentier, C., 1932
Published paleontological determinations.
16- Caton-Thompson, G., 1938
Studied the Geology and Archaeology of Hadramaut, Southwest Arabia; according to
preliminary notes on Lord Wakefield Expedition.
17- Gardner, E.W., 1939
He and Caton-Thompson, G., wrote an article on Climate, Irrigation and Early Man in
Hadramaut.

3. Conclusions
1- In the First stage (The First Systematic Geological Observation Stage or CARTER,
H.J., Stage.) and the Second Stage (The Hinterland Studies Stage) early maps were
based on photographs and isolated visits, generally to the coastal region.
2- Geologic and stratigraphic relations in the region are complex and it must be
realized that it was not until after world II that it was possible to compile of the
region.
3- This study led to significant improvement in imaging about the geological research
history in the Republic of Yemen, particularly about the first and the most famous
geologists, who worked visits, worked and this has been key to understanding.
4-It is broad in scope so as to serve both the beginning geology major and the under
graduate seeking to learn about or to make him read about the geological research
history work in Yemen.
