Sentence examples for grain framework from inspiring English sources

Increased porosity and decreased grain framework density make dilatant disaggregation bands a suitable pathway for meteoric water influx (Du Bernard et al. 2002), which is commonly associated by clay mineral infiltration and diagenetic alterations (Matlack et al. 1989).

Dilatant disaggregation bands are commonly characterized by small shear displacement, a reduced grain framework density, larger pores and a small porosity increase of up to 8% with respect to the host rock (Antonellini et al. 1994; Du Bernard et al. 2002; Fossen and Bale 2007).

Dilatant disaggregation bands are commonly reported for poorly consolidated sandstones at surface or near-surface conditions (< 1000 m), where minor vertical effective stress is applied to the grain framework (Mandl et al. 1977; Du Bernard et al. 2002; Fossen et al. 2007; McKie et al. 2010).

For nearly five decades, the couple systematically photographed individual industrial structures water towers, blast furnaces, grain elevators, framework (half-timber) houses most of which dated to the 19th century and have since been demolished.

The nature of the pore network formation determines the characteristics of the framework grains, such as grain size and sorting.

The quartz grains have been seen in all the samples to be the main framework grain type.

Further subdivision of both arenites and wackes into three specific sandstone families is based on the relative proportions of three major framework grain types: quartz (Q), feldspar (F), and rock fragments (R for rock fragment, or L for lithic fragment).

Table 2 indicates that the framework grain of thick hard roof sandstone is quartz and feldspar, constituting about 69.7% of the total mass.

However, the studied samples from the different wells show little variation in terms of framework grain composition and sorting, which largely ranges between moderately well sorted to well sorted.

The porosity was decreased by compaction and cementation and then increased by dissolution of the framework grains.

In this study, the observed geological constraints on the reservoir performance Farewell sandstones include the composition and sorting of the framework grains and the diagenetic factors.
