Les tufs pyroclastiques résultent de l’écoulement de fragments pyroclastiques, liquéfiés par l’eau ou par des gaz volcaniques, qui finissent souvent par constituer d’épaisses accumulations dans les vallées et les dépressions. Les matières pyroclastiques formées de cette façon peuvent être composées de «lave vive» solidifiée, de fragments de «lave inerte» issue d’éruptions antérieures, de fragments pyroclastiques également d’éruptions antérieures ou de fragments de roches arrachés aux parois du substrat lorsque les fluides volcaniques montent à la surface. 3, record 2, French, - tuf%20pyroclastique

Parallel lamination - Not all types of lamination have the same mode of origin. Laminae in mud may be formed by periodic changes in the physical or chemical conditions of deposition. Laminae in sand may be produced rapidly and form under various conditions but is commonly related to changes in the paleo-hydrodynamic regime. 2, record 3, English, - parallel%20lamination
Record number: 3, Textual support number: 2 CONT
Parallel lamination was formed at bed-aggradation rates up to 4 mm/s ... and bedload-layer sediment concentration up to 0.36. This observation contradicts the generally held assumption that parallel lamination forms only from low-density flows and at low bed-aggradation rates. 3, record 3, English, - parallel%20lamination
