As we mentioned in the preface of the last special issue (Suzuki et al., 2015), greater interests in submarine resources have been generated recently because many people have realized their high po...
The Dogantarla-Aksaray area is situated in western part of the CAVP. This province contains nine (9) different ignimbrite levels, for which a Late Miocene age is indicated by vertebrates as well as K/...
With the development of society and economy, the issues of environment have becoming the focus of all around the world, especially in the developing countries. In China, on one hand, villagers' income...
A wide range and variety of minerals are used in the pharmaceutical industry as active ingredients. Such minerals may be administered either orally as antacids, gastrointestinal protectors, antidiarrh...
Abstract: The Crystal Packer module in the Cerius2 modeling environment has been used to study the structure of montmorillonite intercalated with Al(OH)3-fragment (gibbsite-like) polymers. Basal spaci...
Abstract: The structure of montmorillonite intercalated with [Al13O4(OH)24+x(H2O)12−x](7−x)+ cations ( A l 13 (7−x)+ for short), where x = 0, 2 and 4, has been studied using the Ceri...
Abstract: Transgression by the Western Interior Sea during the Late Cretaceous in southwestern Minnesota caused swampy conditions to be imposed upon a laterite consisting of gibbsite, goethite and kao...
Abstract: An Fe-berthierine occurs in a buried laterite from the Late Cretaceous (Cenomanian) in southwestern Minnesota. It formed beneath a lignitic horizon in which reducing solutions percolated thr...
Abstract: The adsorption of olefins at 25 °C in gas- or vapor-solid systems on 4 clays dried at 120 °C was studied by infrared spectroscopy. Products of condensation have the spectra of paraffinic oli...
Abstract: The adsorption-condensation of olefins was studied on 7 adsorbents: 2 commercial clays, a natural clay and its protonated form, ャ-alumina and porous and nonporous silicas. These adsorbents w...
Abstract: A new model for the interpretation of dioctahedral mica infrared (IR) spectra in the OH stretching vibration region is proposed. It is based on the analysis of the main factors responsible f...
Abstract: A large and representative collection of clay-size dioctahedral mica minerals differing in their chemical compositions has been studied by infrared (IR) spectroscopy in the OH stretching vib...
Hectorite and saponite are exchanged with [Al13O4(OH)24(H2O)12]7+ and the amount of Al3+ adsorbed and Na+ released are followed as a function of the exchange conditions. On saponite the reaction is a ...
Saponite, hectorite, and laponite have been pillared with cationic Al clusters, and special attention has been given to the solution chemistry or Al. Pillared saponite is obtained after exchange with ...
