layered complex

[¦lā·ərd ′käm‚pleks]
(geology)
An igneous rock body of large dimensions, 5-300 miles (8-480 kilometers) across and as much as 23,000 feet (7000 meters) thick, within which distinct subhorizontal stratification, or layering, is apparent and may be continuous over great distances, in some cases more than 60 miles (100 kilometers).

Sama believes that ultramafic sequences of the recently outlined large Yacouba Layered Complex which hosts the Yepleu and Samapleu Nickel-Copper-Palladium deposits and occurrences, are extending within the Zoupleu Permit and as such represent a prime target for nickel-copper-palladium mineralization.
However, recent reports based on virtual histology intravascular ultrasound [6] and OCT [7] have revealed a high prevalence of layered complex plaques, which may represent organized thrombi and could be a significant component of the accelerated intimal thickening in HTx patients.
Therefore, future histological studies should address if layered complex plaques are associated with organized thrombosis.
The garnetiferous biotite gneisses (khondalites) and the associated layered complex of garnetiferous quartzo-felspathic granulites (leptynites) and non-garnetiferous quartzo-felspathic granulites (alaskites) constitute an assemblage of metasediments injected by granitic materials, and recrystallised under deep-seated palingenetic conditions into a migmatite complex.
Isozaki's concept sketches show the museum taking shape as an organic form that wraps around an existing block to provide a defining image for the academy and a layered complex of interconnected display areas.
ULTRABASIC-BASIC INTRUSIVE VIZCAINO LAYERED COMPLEX AND VIZCAINO OPHIOLITE (SOUTHERN BAJA CALIFORNIA, MEXICO)
(I) the main ultrabasic-basic sequence, the Puerto Nuevo Sequence (harzburgite, dunite, cyclic units of dunite, pyroxenite and gabbro) of the Vizcaino Peninsula, is not an obducted slab of oceanic lithosphere; it is instead a part of a layered complex, the Vizcaino Layered Complex, which also includes, upwards, isotropic gabbros, diorites (La Pintada Sequence);
(11) the Vizcaino Layered Complex is related to a magma underplating of continental crust, sensu Fyfe (1992);
(III) the San Hipolito Formation (Zone) belongs in a different, allochthonous, tectonic unit, the San Hipolito Nappe, emplaced upon the Vizcaino Layered Complex during the Liassic (Radelli, 1994, 1995),
These include the Stillwater layered complex in the US (MM, November 1999, pp.290), the Cu-Ni-PGE sulphide deposit in Sudbury (Canada) and less economic placer deposits such as those in Colombia, Ethiopia and the Urals.
It contains the largest deposits of platinum and chromium in the world and is the largest layered complex on Earth (Anhaeusser and Maske, 1986).
Pran extols the four-year collaborative process of design and construction in which the tension between two cultures and three different firms, plus a visionary client and expert consultants, created an audacious, richly layered complex. It occupies the end of the main runway, which runs east-west towards the fjord, providing a poetic symbol for a company that brings people together, as the airport did in the previous century.
