Photogeology

…Textured landforms are formed by differences in rocks (including differences between sedimentary, igneous, and metamorphic rocks, as well as their respective chemical compositions and textures) and by geological structures in a broad sense (horizontal layers, layers displaced or deformed by faults or folds, the presence or absence of structures such as faults, joints, and bedding, and differences in density). In a sense, all eroded landforms can be said to be textured landforms. Photogeology is a field that focuses on textured landforms, and it attempts to determine geological differences from the characteristics of textured landforms seen on aerial photographs, such as differences in the shape of valleys and slopes, differences in drainage patterns, the presence or absence, density, and direction of linear structures. Below are some examples of textured landforms. …

…　組織地形は，岩石の差異(堆積岩，火成岩，変成岩の差やそれぞれの化学的組成や組織の差を含む)や広い意味での地質構造(水平層か，断層や褶曲による変位･変形した地層か，断層･節理･層理などの構造の有無や密度のちがい)などにより形成され，ある意味ではすべての浸食地形が組織地形であるともいえる。谷や斜面の形のちがい，水系模様の差，線状構造の有無や密度，方向性など，空中写真上にみられる組織地形の特徴から地質の差異を判定しようとする写真地質学photogeologyは，組織地形に注目した分野である。以下に組織地形の若干の例を挙げよう。…
