| The sample was taken from a thin limestone lens with phosphatic oolites within the phosphatic greensand. |
|
| The students of these obscure phosphatic scraps were thus much in demand as petroleum stratigraphers. |
|
| The basal part of the transgressive sandstone contains erosion surfaces, reworked bioclasts, phosphatic and glauconite pellets. |
|
| Bed 4 comprised medium grey fossiliferous mudstone with limonitic ooids and phosphatic nodules. |
|
| Conodonts are an extinct group of marine organisms whose preserved skeletal parts consist of tiny phosphatic tooth-like elements. |
|
| They sometimes are found together with dolostone concretions, barite nodules, or phosphatic nodules. |
|
| In time the combination solidifies to a phosphatic rock that, in crumbling, provides soil in which vegetation may take root. |
|
| Other phosphatic and phosphatized microfossils were recovered by dilute acetic acid digestion. |
|
| Three recipe types are recognised namely, hard-paste Si-Al-Ca, phosphatic, and high-magnesium bodies. |
|
| Rocks of late Precambrian and early Paleozoic age have yielded a variety of tiny spine-like fossils of dominantly organic or weakly phosphatic composition. |
|
| The diminution of marl seam thicknesses over positive structural elements and the development of phosphatic chalks in localized troughs are two such features. |
|
| Nodules rich in phosphatic material are found in residual accumulations along disconformities, such as bone beds or lag deposits in marine limestones and shales. |
|
| These included the gastropod Turritella alabamiensis, which was mainly represented by phosphatic internal molds. |
|
| Phosphorus is bound in apatite of lingulate brachiopods Paterina and Mickwitzia and phosphatic pebbles. |
|
| There was also a sizeable increase in the sales of phosphatic and potassic fertilizers as the Company continued its efforts to promote balanced fertilization. |
|
| Siliciclastic material is mostly represented by clay, except in the Aseri Formation, where phosphatic or goethitic ooliths and admixture of quartz sand are recorded. |
|
| Phosphatic nodules, large dolostone septaria, iron sulfide nodules, and crystal-lined vugs are present. |
