1 A siliceous volcanic ash used to produce hydraulic cement.

2 Gritrock is siliceous sandstone.

3 Compared with that of limestone, the properties of siliceous material will have more influence on the burnability of raw meal.

4 Diagenetically authigenic minerals are dominantly kaolinite, chlorite, siliceous, and ferruginous calcite.

5 L Siliceous soil - Soil composed of acid rock that are crystalline in nature.

6 The calcines of siliceous zinc sulfide concentrates were treated hydrometallurgically.

7 The Pre - cambrian alumino - siliceous slate is the host rock of antimony deposit inHunan.

8 Sedimentation - exhalation siliceous rocks are of great significance in the study of ore deposits.

9 A siliceous sandwich layer for separation of ladle lining has been developed by using siliceous sand as main material.

10 The host rock conformably overlies a band of siliceous chertybrecia.

11 The thin bedded siliceous - rocks include chert and depositional quartz with textures of oolite and pebble.

12 Ordered mesoporous carbon was successfully prepared using siliceous MCM-48 as template, p-toluenesulfonic acid (PTSA) as catalyst, and furfuryl alcohol as carbon source.

13 The siliceous earth is acid-washed, then water-washed until neutral, but not base-washed.

14 Microfossil plants occur in gray banded siliceous rocks in the upper part of the middle member of the middle subgroup of the Yunkai Group.

15 Laminated siliceous rocks in country rocks might represent the nature of the Devonian hydrothermal sedimentary rocks.

16 Ordered mesoporous carbon was successfully prepared using siliceous MCM-48 as template, p-toluenesulfonic acid as catalyst, and furfuryl alcohol as carbon source.

17 The industry waste slag fly ash or the river sand is used as the siliceous material.

18 The ore-bearing rock are mainly fine elastic rocks, breccia of albite-carbonate and carbonaceous- siliceous argillaceous rock.

19 The strong silicified rock is a product of metamorphism and siliceous metasomatism of granite genetically correlated with Pangushan wolframite deposit.

20 The investigations on the Upper Changhsingian deep-water deposits in southern Guangxi, South China allow us to trace, an abundant,(www.Sentencedict.com) diverse and well-preserved siliceous sponge spicule assemblage.

21 The two early Carboniferous fragments are composed of Basalt and ash-black, fuchsia radiolaria silicalite, siliceous mudstone, tuff.

22 The main kinds of rocks include carbonate rocks , tuffite, siliceous rocks and quartz sand - stone.

23 The Miaohe-type biotas occur in the black shale and siliceous shale in the transitional areas from the late open platform facies to deep-water shelf-bathyal facies.

24 Its materials might come from both magmas and host rocks, indicating that it was formed when the ichor (or hydrothermal solution) replaced the Devonian siliceous shale and so on.

25 In the melange zone there occur Devonian island arc-type intermediate and intermediate-acid volcanic rocks, which conformably overlie siliceous pelite.

26 LST reef characterized by ag gradational bioherm or patch reef, is generally associated with mixed clastic turbidite, siliceous limestone and mudstone.

27 Gold mineralization of the zone is confined only to the Cambrian carbonaceous shale overlain by siliceous rocks, and apparently controlled by a premineral tough shear zone.
