Xenotime is an igneous and metamorphic mineral just like most other minerals described here. It is resistant to weathering and occurs often in the heavy mineral fraction of sands although it is often misidentified as zircon. Xenotime is elongated and usually colorless, yellow or light brown. Rutile
The Official Website of Embassy of Sri Lanka in Egypt. Sri Lanka’s independence from British rulers on 4th February, 1948 and Egypt’s revolution in July 1952 paved the way for further strengthening bi-lateral relations. Formalizing diplomatic relations, the two countries established their diplomatic Missions in respective capitals, Colombo and Cairo in 1957.
Abstract. This study includes determination and discussion of the texture and heavy mineral compositions of some modem Nile Delta coastal sands (river, coastal dune, beach-face, and nearshore marine) in order to delineate the process and factors that regulate the size distribution of heavy mineral grains comprising these coastal sands.
