These notes, which summarize part of over ten years of laboratory work, aim to clarify and inter-relate three fundamental concepts of current Metallogeny: consanguinity, heritage, province. --1. The concept of "consanguinity": its criteria, limits and graduations, are first presented; 2. They are illustrated by the analysis of a complex example: the lead-zinc mineralisations in Trias around the C4vennes (South of the French Massif Central); 3. The likelihood of consanguinity for various strata-bound mineralisations, particularly misappreciated and misinterpreted, is then shown: --tungsten in the C4vennes -gold at Passagem (Brazil), about which microstructural and geochemical arguments are especially employed --cobalt at Bou Azzer (Marocco) ; 4. From consanguinity in a sedimentary environment, the authors turn to the crustal phenomena cycle, during which the heritages of the cations succeed one another.Examples of heritages, linked with sedimentation-volcanism: Sierra de Carthagena (Spain) --metamorphism --granitisation, are rapidly examined or referred to in literature. Particular attention has been paid to heritage by secretion, illustrated by the antimony lodes of the French Massif Central. Consequently, it may be understood how the successive heritages invoive geochemical permanences and determine the geochemica! provinces going back to ancient times in which the mineralprovinces were built up. 5. In a last section the transformist guideline is compared with other concepts and tools of Metallogeny: lineaments and isotopic ratios. --In conclusion, the intra-crustal heritages still remain under-estimated and badly deciphered and are not sufficiently taken into consideration in mineral exploration.Diese Ver6ffentlichung, die einen Teil der w~hrend eines Jahrzehnts in einem Laboratorium ausgeftihrten _Arbeiten kurz behandelt, hat die Aufgabe, drei Grundbegriffe der gegenwfirtigen Metallogenese klarzustellen und miteinander zu verkntipfen: ,,Familiarit/it" (Verwandtschaft), Vererbung und Provinz. --1. Der Begriff der Ver~vandtschaft sowie seine Kriterien, Grenzen und Nuancen werden zuerst auseinandergese~zt. 2. Dann wird dieser Begriff anhand der Analyse eines komplizierten Beispiels veranschaulicht, und zwar der Blei-Zink-Mineralisationen in der Trias am Rand der Cevennen, im Siiden des franz6sischen Zentralmassivs gelegen; 3. AnschlieBend wird die Wahrscheinlichkeit der Verwandtschaft for verschiedene schichtgebundene, besonders Some Major Concepts of Metallogeny verkannte und falsch interpretierte Mineralisationen aufgezeigt. Es handelt sich einerseits um das Wolfram der Cevennen sowie das Kobalt yon Bou Azzer (Marokko) und andererseits urn das Gold yon Passagem (Brasilien), zu dessert Erklfirung insbesonders rnikrostrukturelle und geochemische Argumente herangezogen werden; 4. So gelangt man in den Kreislauf der Krustalerscheinungen, wfihrenddessen Vererbungen von Kationen aufeinanderfolgen. Beispiele yon Vererbungen, die an Sedimentation, Vulkanismus (Sierra von Cartagena, Spanien), Metamorphose und Granitisie...
