The Miocene of the Madrid basin includes relatively abundant silica rocks (cherts, opals and opaline cherts), which were used during the Palaeolithic and Neolithic to make lithic tools. This work establishes the chemical characteristics that can be used to classify those silica rocks on the basis of their geographical location, explaining at the same time their mineralogical, petrological and geochemical features. The geographical classification of silica rocks is very useful to define the sourc...

The Rubian magnesite deposit (West Asturian—Leonese Zone, Iberian Variscan belt) is hosted by a 100-m-thick folded and metamorphosed Lower Cambrian carbonate/siliciclastic metasedimentary sequence—the Candana Limestone Formation. It comprises upper (20-m thickness) and lower (17-m thickness) lens-shaped ore bodies separated by 55 m of slates and micaceous schists. The main (lower) magnesite ore body comprises a package of magnesite beds with dolomite-rich intercalations, sandwiched between slate...

Abstract Lacustrine and alluvial carbonate facies have been investigated in Middle Miocene successions of the western side of the Madrid Basin in order to evaluate paleoenvironments in which carbonates formed. Carbonate facies are varied and include: (1) calcrete and dolocrete; (2) pond deposits; (3) lake margin dolostone; (4) mudflat carbonate; and (5) open-lake carbonate facies. The dominant mineralogy of these is dolomite and/or low-Mg calcite. No high-Mg calcite or aragonite have been detect...

A detailed study of the specific surface area (SSA) and the volume of pores between 10 A and 400 A (ultramicroporosity -UMP-) in different types of silica phases is carried out in this paper. The samples were chosen from different locations and geological settings, with an emphasis on high silica content (above 80%) and mineralogical simplicity (one silica phase predominates in every sample). Some samples belong to continental siliceous rocks and silcretes of the Miocene age, and others to radio...

The Cathedral of Toledo, built over a long period of time, includes a wide variety of stone materials which have been carefully studied and compared with similar, nonweathered samples from old quarries. Different techniques were used to determine their degree of weathering: thin section analyses, electron microscopy, x-ray diffraction, chemical analysis, and ultrasound surveys. The authors also studied the environment of the cathedral by means of automatic pollution monitoring equipment and a me...

Abstract Fe, Zn, Sr, Ba and Pb contents are reported for carbonate and non-carbonate (clay) fractions of Lower Cretaceous limestones and dolostones from western Cantabria. Spain. Increases in the Zn contents of both carbonate and non-carbonate fractions are observed in association with the calcite-dolomite transformation, suggesting that the dolomitising fluids were probably enriched in this element. Relationships between regional geochemical trends for some elements (Zn in the carbonate fractio...
