| They conclude that carbonate concretionary growth occurs over a depth range from tens to hundreds of metres of burial. |
| A sort of concretionary affinity comes into play, and the different chemical units congregate together. |
| Those sections expose concretionary mudstones interbedded with thinner quartz sandstones, limestones, and marl. |
| The prevalence of crystalline, concretionary and drusy structures in dolomite can thus be simply explained. |
| In deposits of this nature in South America these concretionary masses form distinct beds. |
| These chemical changes may be the cause of the frequent concretionary structure and veining in the laterite. |
