It has been 10 years since publication of the first edition ofSoils of the Past. In that time the
subject of paleopedology hasgrown rapidly, and established itself within the mainstream …

This chapter reviews the basic mineral characteristics of palygorskite and sepiolite, as well
as discusses the means for their identification, and their origin. Emphasis will be placed on …

Several studies have highlighted the importance of collecting well-dated records of
palaeoenvironmental changes on desert margins, particularly in the semi-arid interior of …

The origin of sedimentary dolomite is a subject of long-standing enigma that still awaits
resolution. Previous studies have shown that room temperature synthesis of abiotic dolomite …

Arid soils in central Iran that evolved from the weathering of post-Tethyan sediments contain
palygorskite. Clay fractions of gypsiferous soils and their associated sediments from different …

Most bulk chemical analyses of sepiolite and palygorskite available in the literature are
erroneous because samples analyzed are admixtures of minerals that are difficult to …

The structure and chemical composition of sepiolite and palygorskite are known from the first
half of the twentieth century. Ideal palygorskite Si 8 O 20 (Al 2 Mg 2)(OH) 2 (OH 2) 4⋅ H 2 O) …

Palygorskite and associated clay minerals have been studied in a Pleistocene calcrete
complex from the Negev desert (Sde Boqer, Israel). This complex is divided into five main …

Lower Permian strata have been extensively cored in the subsurface of the Bravo Dome
field, northeastern New Mexico. Analysis of core indicates that these strata consist of …

In the long continental history of the Provence Basin which extended from Santonian to
Oligocene times, a major period of palaeosol development occurred in the Danian …
