If quartz arenites are first-cycle deposits, they must form under weathering, transport, and depositional conditions so vigorous that most grains chemically and mechanically less stable than quartz are eliminated (see, for example, Johnsson et al., 1988). Moving lower on the centrefold page, I have tried to illustrate most of the common rock types. Particles are dispersed in a suitable electrolyte and forced to flow through an aperture one at a time.

Clastic sedimentary rocks, such as breccia or sandstone, were formed from rocks that have been broken down into fragments by weathering, which then have been transported and deposited elsewhere. In water deep enough not to be affected by surface wave action the clay fraction begins to settle out. Sedimentary rocks contain the fossil record of ancient life-forms that enables the documentation of the evolutionary advancement from simple to complex organisms in the plant and animal kingdoms.

Opal occurs primarily in Tertiary and younger sediments. When you've found the plate that matches yours, grab the piece of paper in the label pile and set it on to your tectonic plate. 6. This produces cross-bedding, lamination which is inclined to the bed surfaces at angles up to 30°-35°, the maximum angle of stability for a pile of loose grains. Sabkhas commonly do not consist entirely or even dominantly of evaporites.

Quick cooling means that mineral crystals don't have much time to grow, so these rocks have a very fine-grained or even glassy texture. By deposition time, they've usually been reduced to stable end-products �quartz sand, clay mud and dissolved carbonate. Faint slickenlines are apparent on some of the fault surfaces. Igneous rocks display a slice across the sequence. The Laramide intrusions are tagged "TKi" and mapped in a dark purple, while the mid-Tertiary intrusions are marked "Tmi" in hot pink.

Explanations: A - folded rock strata cut by a thrust fault; B - large intrusion (cutting through A); C - erosional angular unconformity (cutting off A & B) on which rock strata were deposited; D - volcanic dyke (cutting through A, B & C); E - even younger rock strata (overlying C & D); F - normal fault (cutting through A, B, C & E). Whether or not some dolomites are primary is a problem not yet adequately resolved.

Classification of siliciclastic rocks based on the four compositional components quartz, feldspars, lithics, and matrix (modified from Williams, Turner, and Gilbert, 1982). Some available data are summarized in Table 6.3. There are a lot of different ways to categorize sedimentary rocks. A.

Some magnesian calcites may contain as much as 30 mol% MgCO3 (Veizer, 1983).

I will add links to the others as I write them: At the bottom there is some more information on types of properties like crystal habit, hardness and lustre. Quartz is by far the most common of these stable. Over time these rocks will recrystallize, developing a more interlocking crystalline texture (fig. 3). The Mississippi delta in Louisiana deposits lots of sediment in the Gulf of Mexico! The Muav Limestone was deposited around 530 million years ago at the bottom of a shallow sea.
