Renowacja i konserwacja kamiennej płyty z tropami dinozaurów w rezerwacie przyrody Gagaty Sołtykowskie

Rembiś Marek, Dźwigulska-Musiał Paula

Przegląd Geologiczny

2021

Vol. 69, nr 2

91--96

The inanimate nature reserve Gagaty Sołtykowskie is located in the northern part of the Permian-Mesozoic margin of the Holy Cross Mountains, within the abandoned Odrowąż quarry. Trackways of dinosaurs have been printed on a sandstone bedding plane within the Lower Jurassic (Hettangian) Zagaje Formation. The tracks are the oldest known evidence of a group life of the herbivore (plant-eating) sauropods andofa hunting group of predatory the ropods. After twenty years of being exposed to visitors, the sandstone layer had to be thoroughly renovated and conserved. On the basis of an evaluation of its state of preservation followed by laboratory examinations, the authors have prepared the program of conservation procedures and established a set of appropriate materials. The surface of the layer has been cleaned and its loose fragments fixed with the Injektionharz 100 (Remmers) glue. The layer has been impregnated and fractures sealed with an organosilicon compound KSE 100 and KSE 300 (Remmers). The tracks of dinosaurs have become more vivid due to their saturation with the mixture of the KSE 300 and a mineral pigment.

Łukasiewicz Jadwiga

The paper discusses ethical guidelines in relation to the conservation of historical monuments made of stone. The presented rules consider the building stone specificity and its susceptibility to various corrosion factors and the character of deteriorated areas in that kind of historic monuments. The basic conservation rule sounding Primum non nocere is deconvoluted to more particular principles like: (i) to preserve authentic historical matter as a carrier of artistic, scientific and historical value of the object, (ii) to provide minimal scale of intervention, (iii) to provide the reversibility of the methods and particularly materials used from conservation or reconstruction works, (iv) to provide distinguishability of reconstructions parts and (v) to provide the integrity of the work of art. The adaptability of these particular rules to the of conservation of stone artistic artefacts is also presented.
