Minerals of the Teschenite Association Rocks in the Beskydy Piedmont Area (Czech Republic and Poland) – A Review

Early Cretaceous igneous rocks in the Podbeskydí area (Czech Republic and Poland) are investigated since their first mention in 1816. Since than, significant number of published papers, as well as monographies, explanatory notes to the geological maps, student theses, unpublished reports, and other documents appeared. They are shivered in many languages – the older ones are mostly in German, later followed by the Czech, Polish, French, and in recent two decades mostly in English. While the availability of old publications is getting better than ever, meaning of both geological and mineralogical terms sometimes shifted, so it might be problematic to understand properly even with easily accessible machine translations. For this reason – to acknowledge what was done in the past, to demostrate the present state of knowledge, and to point out what should be done in the future – we produced the following text. This review presents a summary of mineralogical works, with critical comments on necessary cases. New investigation including some yet unpublished results is also included. In general, we can say that the approximate numbers of valid mineral phases in groups of the Nickel-Strunz classification systems are as follows: elements – 1, sulfides – 8, halides – 2, oxides – 18, carbonates – 9, sulfates – 12, phosphates and vanadates – 11, and silicates – 81. Out of these numbers, ca. 60% was described in last 40 years, and and ca. 45% in last 20 years. So it is clear that the research is continuously improving our knowledge about the mineralogy of the Teschenite Association Rocks and significant focus on this rock suite is going on recently.
