In geology, a terrane (/ təˈreɪn, ˈtɛreɪn /; [1][2] in full, a tectonostratigraphic terrane) is a crust fragment formed on a tectonic plate (or broken off from it) and accreted or "sutured" to crust lying on another plate.

The meaning of TERRANE is the area or surface over which a particular rock or group of rocks is prevalent.

2023年11月23日 · A terrane is a part of a landmass, bounded by tectonic faults, which is different in many ways from the main landmass to which it is attached. Schematic diagram of terrane docking.

2020年2月11日 · Accreted terranes are the blocks of continental fragments and oceanic islands that have collided with a continent and are now permanently attached. All continents, including North America, tend to be older in their interiors and grow outward over geologic time, as terranes are added to the edges of the continent.

2020年1月30日 · A terrane is a group of related rocks that formed together in one area, do not show any relationship to the other rocks around them, and are separated from the rocks around them by faults.

A terrane is defined as a fault-bounded block containing rocks that have a distinct geologic history compared with contiguous blocks. From: The Sedimentary Basins of the United States and Canada (Second Edition), 2019

Knowledge of fractured rock geology, or “terrane,” provides important context for investigating contaminated sites. Tectonic forces impart characteristic structures on rock formations that influence the evolution of the landscape, groundwater flow, and contaminant migration.

2016年1月1日 · Terranes are regions within an accretionary orogen that are characterized by rock assemblages of internal geological consistency that differ from assemblages contained in adjacent terranes.

2022年4月4日 · “Terrane” describes a crustal fragment consisting of a distinct and recognizable series of rock formations that has been transported by plate tectonic processes, whereas “terrain” describes the shape of the surface topography.

…composed of separated microcratons, or terranes, that appear to have been attached or adjacent to the northern margin of Gondwana. The coalescence into present-day Asia took place after the Devonian. Devonian rocks are well known to fringe the central Siberian craton (a Devonian microcontinent), particularly in some of the northern…
