The women enrolled into the second part of the INTERGROWTH 21st Project -- whether in Pelotas, Brazil, or Nagpur, India -- were carefully selected to achieve a like-for-like comparison: urban women of similar age with a healthy BMI who were non-smokers and living in a clean environment.
Restriction of food intake and inappropriate nutrition practices in combination with environmental and socioeconomic factor and infections is common causes of maternal mortality, low birth weight, and intergrowth retardation [15, 16].
Kaolin samples from Alumbres contain significant amounts of opaque minerals with a crystalline cubic system, such as pyrite, some coarse grits intergrowth with iron oxides on strongly oxidized clay, and high developments of metallic pyrite minerals, as is shown in Figure 4(a); therefore, this represents a hydrothermal alteration area [21].
Mineralization of the Dahu deposit has been divided into four stages [22]: an initial quartz-K-feldspar stage (I) characterized by milky quartz and pink K-feldspar and minor coarse-grained (>5 mm) euhedral pyrite, anhydrite, celestine, covellite, rutile, and molybdenite (Figure 2), a pyrite-molybdenite stage (II) characterized by intergrowth of fine to very fine-grained (0.005-1 mm) pyrite and molybdenite, a sulfide-telluride-sulfosalt-gold stage (III) characterized by abundant galena and chalcopyrite and accessory celestine, native gold, tellurides, and Bi-sulfosalts (Figure 2), and a final barren carbonate-dominated stage (IV).
These two main minerals are in tight intergrowth with unstructured solid organic matter, kerogen, altogether composing the pure mudstone oil shale.
Extremely fine intergrowth between galena and sphalerite minerals inhibits selective flotation separation and favours bulk flotation.
Conversely, the magnetic, non-magnetic and red earthy gravels became cemented only through impregnation and intergrowth of Fe-Mn-Al oxides.
Finally, the presence of irregular to rounded micritic carbonate clasts, which sometimes include smaller quartz and feldspar grains and sometimes show intergrowth with clays and oxides/hydroxides, would be indicative of reworking processes (Fig.
It occurs through most of the sample as an intergrowth with dolomite (15-75%) rhomb sections (Figures 4a-b, 8d-f).
The intergrowth of quartz and moganite polymorphs of Si[O.sub.2] is typical for agate structures (Heaney and Davis, 1995).
