  Publikacja

  • E. Wagner-Wysiecka

  - Journal of Gems & Gemmology - Rok 2023

  Succinite, Baltic amber, is one of the most appreciated fossil resins. Its beauty has fascinated people since prehistoric times. It is a substance, and also gemstone, whose uniqueness is due to its compelling, though still not fully understood, physicochemical nature. In this article, some facts about the physical and chemical properties of succinite in order to find an answer for questions about the unique properties of this resin,...

  - SPECTROCHIMICA ACTA PART A-MOLECULAR AND BIOMOLECULAR SPECTROSCOPY - Rok 2018

  Natural Baltic amber (succinite) is the most appreciated fossil resin of the rich cultural traditions dating back to prehistoric times. Its unequivocal identification is extremely important in many branches of science and trades including archeology, paleontology, chemistry and finally mineralogical and gemological societies. Current methods of modification of natural succinite are more and more sophisticated making the identification...

  Wysokorozdzielcza fotografia cyfrowa i analiza obrazu graficznego została zastosowana w celu zdefiniowania zewnętrznych cech morfologicznych deformacji muszli w czterech populacjach małży bałtyckiej Macoma balthica z Zatoki Gdańskiej. Proponowane indeksy deformacji małży (shell deformation indices - SDI), które opierały się na obliczeniu stosunku wybranych średnic przednich i tylnich części małży, ukazały przynajmniej trzy morfologiczne...
