Preliminary Notes on the Geology of Kutch, Western India, resulting from the 
examination of that district, now in progress, hy the Officers of the Geological Survey, 
by A. B. Wynne, E. G. S., &c. 
The detailed examination of this province has been long looked forward to with interest, 
as promising to east light upon the geology of other parts of India where fossil land 
plants similar to some of those occurring in Kutch have been found to characterize an 
extensive group of rocks and are almost the only fossils which those rocks contain. 
These plants were known to he associated in Kutch with a large number of marine 
fossils, the Jurassic age of which was determinable, but the relations between the beds con¬ 
taining forms so distinct had still to be ascertained. 
With this view a hasty visit was made to the district of Kutch by Mr. W. T. Blanford 
of the Geological Survey, in 1863, and the conclusions to which his observations led appeared 
in a short paper among the publications of the Survey. (Vol. VI, pt. 1.) 
Except this comparatively recent paper other sources of information regarding the geology 
of the country, prior to the present investigations, were almost limited to a paper by Captain, 
since Major, Grant, read before the Geological Society of London in February, 1837 ; some 
remarks upon it hy Dr. Carter in “Geological Papers on Western India" published by_the 
Bombay Government in 1857; a record of some fossils by Colonel Sykes (Geological Society, 
London), and an interesting notice in Sir Chas. Lyell’s “ Principles of Geology,” describing 
the effects of the earthquake of 1819, the elevation of the “ Allah Bund,” and submergence 
of Sindree village on the Runn, north of Lnkput. 
Of these Captain Grant’s paper is the most detailed, but while it contains many 
valuable facts, several of these seem to have been affected to distortion Joy geological theories, 
or views, which have vanished since he wrote, and also by a misappreciation of the stratigra¬ 
phic arrangement of the rocks. The four or five-fold sub-division adopted by him, being 
natural, is correct, though the sequence was mistaken. 
The Rocks classified. 
The following may indicate the ultimate arrangement of the larger rock-groups, some of 
the newer ones being perhaps capable of further sub-division : 
C Blown sand. 
Recent and Sub-recent ... J Alluvium. 
Tertiary 
Stratified traps and Intertrappean. 
Upper Jurassic (F Rajmabal.) 
Lower Jurassic (“ Dogger," or Middle Jurassic.) 
Jurassic 
Intrusive Traps. 
[The syenite of Parkur-Nuggur, Kalinjur hill, &c., at the north-east corner of the 
Runn might he added to the above as the nearest base known for the Jurassic rocks ]
