A cluster of four kimberlite bodies was discovered on the left bank of the Penner River near Timmasamudram village. Falling in the area known for alluvial diamond occurrences within the Wajrakarur Kimberlite Field (WKF), this cluster is located between the Kalyandurg Kimberlite Cluster in the west and Chigicherla Kimberlite cluster in the east.
The Mesoproterozoic Narayanpet Kimberlite Field (NKF) is located ~200 km north of the well-known Wajrakarur Kimberlite Field (WKF) in the Eastern Dharwar …
The kimberlite in this newly discovered intrusion (here referred to as Pipe 15) is characterized by a magmatic, microcrystic rock texture, consisting of microcrysts …
Systematic closely spaced geological traverses conducted in the year 2010, in Lattavaram Kimberlite Cluster (LKC) of Anantapur district, Andhra Pradesh, India, have led to the discovery of a new ...
The Narayanpet Kimberlite field, that lies southwest of Hyderabad, the capital city of Andhra Pradesh, India, hosts a number of kimberlite pipes. These pipes appear to be randomly positioned. However, based on regional geologic structures revealed by Bouguer gravity anomalies, especially in a regional gravity map, their locations form a definite …
Kimberlite is known for hosting diamond and also has its own petrogenetic importance. Satellite-based studies used spectral feature of 'serpentine' as a criterion for spatial mapping of kimberlite21. However, the roles of texture, grain size and optical coupling of different spectral features of the associated minerals in influencing the ...

Note mafic microgranular dyke (MMD). (e) Granite-chloritised kimberlite breccia, ultramafic lamprophyre at Khaderpet. (f) Old shaft of gold mine at ...
In order to delineate the kimberlite bodies, gravity and magnetic surveys were undertaken in the Panna Diamond Belt, Madhya Pradesh, in Central Indian Diamond Province. The Panna Diamond Belt lies in the Baghain formations of Kaimur and Rewa group of rocks. The Bouguer anomaly map was based on a total of 259 gravity …
This paper serves to report, for the first time, on the chemical composition of primary groundmass minerals occurring in a newly discovered kimberlite located 150m NE of the well known Pipe 2 kimberlite in the Wajrakarur cluster of the Wajrakarur kimberlite field, Eastern Dharwar craton, Southern India. These mineral compositions are also …
New areas for kimberlite search based on gravity data in Andhra Pradesh. A conceptual geological model for the exploration of kimberlite was proposed based on the study of …
The Wajrakarur Kimberlite Field contains 35 Kimberlite pipes within four clusters viz. Wajrakarur-Lattavaram (P1-P17), Kalyandurg (KL1-KL7), Timmasamudram (TK1-TK6) and Chigicherla (CC1-CC5 ...
Delineation of kimberlite pipe is an important step for diamond exploration. In general, conventional exploration methods, such as indicator minerals survey, field based systematic mapping, are ...
