Mineral assemblages as a record of the evolutionary history of the Pepper Mts. Shale Formation (the Holy Cross Mts.)
(Wydawnictwa AGH, 2016) Naglik, Beata; Natkaniec-Nowak, Lucyna; Heflik, Wiesław
The Pepper Mts. Shale Formation, consisting of: clayey shales, mudstones and sandstones, as one of the oldest unit of the Holy Cross Mts., was subjected to mineralogical and petrographical studies. In order to reconstruct the geological history of the succession, mineral assemblages were characterized from the genetic point of view. Pyrite and goethite taking a form of bacterial-cell pseudomorphoses, crystallized during sedimentation and/or diagenesis, while quartz, kaolinite, goethite and chlorite prove subsequent alteration due to the hydrothermal fluid circulation. Secondary sulphates occurring on the pyrite-bearing rock outcrops mark the way of weathering processes. According to the presented results, Cambrian sediments were affected by hot fluids, which caused mineral recomposition and maturing of organic matter. Under the hypergenic conditions sulphate crust precipitate with pickeringite $[MgAl_{2}(SO_{4})_{4} \cdot 22H_{2}O]$, as a dominant phase accompanied by alunogen $[Al_{2}(SO_{4})_{3} \cdot 17H_{2}O]$ and small amount of epsomite $[MgSO_{4} \cdot 7H_{2}O]$.

Larimar – a unique pectolite rock from the Dominican Republic
(Wydawnictwa AGH, 2015) Kowalczyk, Joanna; Natkaniec-Nowak, Lucyna; Wachowiak, Jacek
Larimar, whose colour is varying from white light-blue, green-blue to deep blue, is only found in the Sierra de Bohoruco mountain range, Barahona Province, the Dominican Republic. It was discovered by a Spanish priest, Miguel Fuertes Lorén, in 1916 (Fuertes Marcuello & Garcia Guinea 1990).

Preliminary results of mineralogical investigations of Cambrian rocks from the Pieprzowe Mts. (Sandomierz Upland, Poland)
(Wydawnictwa AGH, 2014) Naglik, Beata; Heflik, Wiesław; Natkaniec-Nowak, Lucyna
The mid-Cambrian rocks exposed in a topographic scarp adjacent to the Vistula River within the Pieprzowe Mts. (Sandomierz Upland, South East Poland) were the subject of preliminary petrological and mineralogical studies.
