Описание слайда:

Sedimentary structures  are utilized to indicate original position (начальная позиция) of strata and understand the depositional environment  (условия осадконакопления) of the sediment. compiled by A.A. Bleim-Stegailo

Описание слайда:

Flow structures There are 2 kinds: bidirectional and one directional. Flow regimes (режим течения), which at varying speeds and velocities(скорость) produce different structures, are called bedforms. (крепление) compiled by A.A. Bleim-Stegailo

Описание слайда:

In the lower flow regime, a flat bed, ripples, dunes are formed. The upper flow regime forms dunes which become flattened out (выравнивает-ся), to become antidunes. compiled by A.A. Bleim-Stegailo

Описание слайда:

Ripple marks Ripple marks are usually formed by flowing water. There are two types: Symmetrical ripple marks - are created by a two way current, f.ex. the waves on a beach (swash and backwash). Asymmetrical ripple marks - are created by one way current, f.ex. in a river, or the wind in a desert. compiled by A.A. Bleim-Stegailo

Описание слайда:

Biological structures Biologically-created sedimentary structures are called trace fossils. Examples include burrows (норы, поры) and various expressions of bioturbation. compiled by A.A. Bleim-Stegailo

Описание слайда:

Soft sediment deformation structures SSD is an afterward of loading (приложение нагрузки) on wet sediments, it continues after deposition. compiled by A.A. Bleim-Stegailo

Within bedding structures These structures are within sedimentary bedding. They are formed when the sediments are deposited.

Краткое описание документа:

Такие презентации мы создаем в геологоразведочном колледже для предмета "Профессиональный иностранный язык". Студенты изучив общую геологию на русском языке, изучают похожие темы на английском языке. Знание терминологии важно на английском языке, т.к. колледж сотрудничает с иностранными компаниями и часть выпускников работает в этих компаниях.

Для облегчения объяснения и восприятия используем такие презентации. Иногда приходится консультироваться со спец.предметниками, чтобы убедиться, что правильно отбираешь материал.
