Ruby has attracted scientific and economic interest. It has already been studied extensively regarding its widespread global distribution and the diversity of its geological associations, as revealed by exploration and exploitation. Researchers are becoming increasingly aware that geographic typing of ruby characteristics and its host assemblages may guide further exploration and provide checks on reputed sources of both rough and cut stones. Genetic pointers, based on fluid and solid mineral inclusions, oxygen and other isotope values and pressure and temperature estimates, have already yielded much genetic information. Rare ruby in mantle xenoliths, TP ~1100o C, 2GPa, epitaxial diamond in ruby and ruby in diamond have special interest. Amid the present extensive documentation on this singular gem mineral, new insights and co-existing associations remain to be discovered. Although ruby largely appears in metamorphic and metasomatic source rocks, newer studies suggest it may also arise from magmatic sources. Age-dating of a range of mineral inclusions in ruby now allows more precise modelling of ruby genesis. Tectonic aspects of ruby genesis related to early collisional plate events on Earth are also a frontier for further understanding. In addition, ruby growth remains an important phase in metamorphic studies of events in some young collisional zones. This Special Issue planned for Minerals aims to attract further studies on this multi-origin gem mineral. Investigations at the 'economic border' of ruby and sapphire nomenclature and relevant treatments affecting ruby color will be considered. 606 $aEarth sciences, geography, environment, planning$2bicssc 606 $aResearch & information: general$2bicssc 610 $aCentral Pamir 610 $aclassification 610 $acorundum 610 $aeskolaite 610 $aexploration 610 $afluids 610 $agemology 610 $agems 610 $agenetic models 610 $ageochemistry 610 $ageochronology 610 $ageographic origin determination 610 $ageology of gem deposits 610 $ain situ U-Pb LA-ICP-MS rutile dating 610 $alinear discriminant analysis 610 $amagmatism 610 $amarble 610 $ametamorphism 610 $ametasomatism 610 $amineralogical association 610 $aMogok 610 $aMontepuez 610 $aMuzkol-Rangkul anticlinorium 610 $an/a 610 $aoxygen isotopes 610 $aradiogenic isotopes 610 $aRb-Sr and Sm-Nd isotopes 610 $aruby 610 $aruby deposits 610 $asapphire 610 $asedimentary 610 $aSnezhnoe deposit 610 $aSouthern Urals 610 $aspinel 610 $astable and radiogenic isotopes 610 $asulfides 610 $aTajikistan 610 $atrace elements 610 $atypology 610 $aU-Pb dating 610 $azircon 610 $azirconolite 615 7$aEarth sciences, geography, environment, planning 615 7$aResearch & information: general 700 $aSutherland$b Frederick Lin$4edt$01323483 702 $aZaw$b Khin$4edt 702 $aSutherland$b Frederick Lin$4oth 702 $aZaw$b Khin$4oth 906 $aBOOK 912 $a9910557697803321 996 $aMineralogy and Geochemistry of Ruby$93035609 997 $aUNINA
