The typologic study of zircon populations from granitic rocks lead to the proposition of a genetic classification with three main divisions: (1) granites of crustal or mainly crustal origin [(sub) autochthonous and aluminous granites)]; (2) granites of crustal+mantle origin, hybrid granites (calc-alkaline and sub-alkaline series granites); (3) granites of mantle or mainly mantle origin (alkaline and tholeiitic series granites). In detail, there are many petrogenetic variants of each of the… 
Petrography and zircon morphology of syntectonic granitoids rocks of Hafafit area, South Eastern Desert (Egypt).
The study deals with the petrography of the granitoid rocks intruding the five (A to E) domes of Hafafit Culmination. The morphological characteristics of zircon crystals are also examined, in order
Zircon typologies and internal structures as petrogenetic indicators in contrasting granitoid types from central Anatolia, Turkey
SummaryThe external zircon morphology of granitoid rocks is combined with internal structures studied by cathodoluminescence imaging, to test the classic ‘Pupin method’ against geological and
Chemistry of Zircon in Rare Metal Granitoids and Associated Rocks, Eastern Desert, Egypt
Typological study, including paragenic, morphological, textural, and chemical characteristics of zircon from nine rare metal granitic stocks and associated greisens, was carried out in order to

Zircon is a very interesting accessory mineral, a kind of ‘crustal diamond’, easily recycled and recording through large morphological variability the main rock-forming events. Since 1985, a
Geology, geochemistry and age of the 'Tricolor' granite and some other Proterozoic (TIB) granitoids at Trysil, southeast Norway
Igneous Belt (TIB) exposed southeast of the Scandinavian Caledonides. In the Trysil-Engerdal area younger granites intruded foliated granitoids (ca. 1800 Ma older Yarmland type) and lower parts of
The Central Anatolian Granitoids (CAG) display distinct petrological characteristics. S-, Hand A-type granitoids, supposed to be related to the continental collision and postcollision stages, were
Geochemical implications for the magma origin of granitic rocks from the Ditrău Alkaline Massif (Eastern Carpathians, Romania)
In addition to a series of ultramafic to mafic and alkaline igneous rocks, a granite body also occurs in the Ditrău AlkalineMassif, Eastern Carpathians, Romania. We present and discuss mineral
Characteristic mineralogy of the Zhutishi granite: Implication for petrogenesis of the late intrusive granite
Many late intrusive granites with strongly peraluminous composition and fine-grained texture occur as stocks or apophysis in the Dadongshan main intrusive granite located in NW Guangdong Province.


Uranium-Lead Isotopic Variations in Zircons: A Case Study
Zircons in a single 250-pound block of Precambrian Johnny Lyon granodiorite from the Dragoon Quadrangle in Cochise County, Arizona, have been concentrated with special attention to yield and nature
Age and origin of the Nigerian mesozoic granites: A Rb-Sr isotopic study
Sixty-four Rb-Sr and two K-Ar isotopic measurements from seven ring complexes in central Nigeria provide evidence for a systematic age trend along a 200 km zone ranging from 174±5 m.y. in the north
Zircons from the Animas stock and associated rocks, New Mexico
Zircons have been studied by measurement of lengths and widths of 200 crystals for each sample. Data are analyzed by the reduced major axis method. Ten samples from the Animas stock, emplaced at
Statistical Studies of Zircon as a Criterion in Granitization
THE opposing views of magmatists and transformists have resulted in a heated controversy on the origin of granite, and a recent conference on this question held by the Geological Society of America1
Palaeozoic and Mesozoic age trends for some ring complexes in Niger and Nigeria
OVER 40 individual granitoid ring complexes exhibiting similar petrological and geochemical variations have been recognised in Nigeria1. They range in size from 1,500 km2 to < 2 km2. The ring
Une typologie originale du zircon accessoire
Les auteurs presentent une methode d'etude statistique nouvelle des populations de zircon accessoire des roches endogenes ; cette methode est basee sur la typologie des cristaux automorphes et
