hyaline element . A conodont element that lacks white matter except, perhaps, along thin growth axes in cusp or denticles; contrasts with albid element; typical fibrous elements are also hyaline, but it is not clear that all hyaline elements are fibrous in structure (TIP, 1981, pt. W, supp.2).
trail of a fault . Crushed material along the fault surface that is used, often erroneously, as an indication of the direction of displacement. Such material can be a source of mineral deposits ( drag ore ). Little used.
longitudinal ridge . One of many closely spaced continuous ridges elongated parallel to the current and developed rhythmically on all or part of a stream bed. Ridges are separated by regularly spaced longitudinal furrows, the separation ranging from 3 mm to as much as 5 cm (Dzulynski and Walton, 1965, p.61). Cf: rib and furrow.
In this episode, host Andrew Geary speaks with John Hudson and Bill Abriel on the upcoming Energy in Data Conference. The conference will take place in Austin, Texas from 17-19 June. Powered by AAPG, SEG, and SPE, this forward-looking conference will include the latest in digital transformation trends as they relate to the energy sector (topics such as machine learning and data management storage), oil & gas development and drilling, production, and more.
Solo el 16% de la energía que fue liberada por el sismo M = 7 se convirtió en ondas sísmicas, que son responsables por el daño. Sin embargo, el sismo produjo la sacudida de roca madre más fuerte jamás registrada. Si más de su energía se hubiera transformado en ondas, su efecto habría sido mucho mayor.
The magnitude 7.1 earthquake, which struck Mexico City on 19 September 2017, caused devastation in the city and its surroundings. 369 people died, 57 buildings collapsed, and a much larger number was seriously damaged.
Jack Boyland is a “freelance” (avocational) paleontologist in New Jersey, who through his field work and discoveries has improved our understanding of the fossil record there. He is affiliated with the Delaware Valley Paleontological Society and the Morris Museum in Morristown, New Jersey. We are pleased to present this interview with him, in which he shares his enthusiasm for all things paleontological.
