Chevron folds are a structural feature characterized by repeated well behaved folded beds with straight limbs and sharp hinges. Well developed, these folds develop repeated set of v-shaped beds. They develop in response to regional or local compressive stress. Inter-limb angles are generally 60 degrees or less. Chevron folding preferentially occurs when the bedding regularly alternates between contrasting competences. Turbidites, characterized by alternating high-competence sandstones and low-competence shales, provide the typical geological setting for chevron folds to occur.

dbo:abstract
  • Chevron folds are a structural feature characterized by repeated well behaved folded beds with straight limbs and sharp hinges. Well developed, these folds develop repeated set of v-shaped beds. They develop in response to regional or local compressive stress. Inter-limb angles are generally 60 degrees or less. Chevron folding preferentially occurs when the bedding regularly alternates between contrasting competences. Turbidites, characterized by alternating high-competence sandstones and low-competence shales, provide the typical geological setting for chevron folds to occur. Perpetuation of the fold structure is not geometrically limited. Given a proper stratigraphy, chevrons can persist almost indefinitely. (en)
  • V形褶皱(英語:Chevron (geology))是一種褶皱結構,具有上下一致重複的折疊層,具有直的褶皱翼和成銳角的褶皱背脊。 若發育良好,這些褶皺兩翼形成 V 形狀相交。 其相交角度通常為 60 度或更小。 它們是受壓縮應力而造成。 構成V形褶皱的岩層通常是由交替不同强度的岩層組成。例如濁積岩的組成,一般以交替的高强度砂岩和低强度頁岩組成。 褶皱的延續是不受幾何限制。 若有適當的地層,V形褶皱就可由壓縮應力造成 。 (zh)
