| 21. | Silicic lava domes are also found.
|
| 22. | The biogenic silica composing the cell wall is synthesised intracellularly by the polymerisation of silicic acid monomers.
|
| 23. | Throughout its complex eruptive history, volcanism shifted from silicic explosive eruptions to voluminous, mafic activity.
|
| 24. | Silicic magma also exhibits this transition between effusive and explosive eruptions, but the fragmentation mechanism differs.
|
| 25. | Torfaj�kull last erupted in 1477 and consists of the largest area of silicic extrusive rocks in Iceland.
|
| 26. | Gold is associated with silicic, kaolinitic, and pyritic alteration of greenschist-grade felsic metavolcanics.
|
| 27. | X-ray microanalysis demonstrated that the numerous scales coating the cell body surface were silicic structures.
|
| 28. | She also has interests in intermediate composition and silicic volcanoes, particularly at Mount St . Helens.
|
| 29. | The magma of Ashi volcano formed by the mixing of trachyandesitic magma with a more silicic component.
|
| 30. | The researchers found that the mirrors slowly broke down into harmless silicic acid in simulated human blood plasma.
