dolomite

1 A lot cephalopoda fossils were found in the section of dolomite with limestone, which belong to early Ordovician.

3 News outlets report the Knoxville school is now selling shirts featuring the boy’s hand-drawn design, which also has been painted onto the Rock , a longtime 97.5 ton campus landmark made of dolomite stone.

4 They are made from different materials——dolomite, tough silk, organdie etc.

它们是用不同的材料做的，白云石、绡、蝉翼纱等。

5 At present, there are proven reserves Slate, kaolin, dolomite, iron ore and so on.

目前已探明的矿藏有板石、高岭土、白云石、铁矿石等。

6 All of the dolomite found in ancient rocks has been formed through magnesium replacing some of the calcium in the calcite in carbonate muds and sands.

7 In mines where limestone is a waste rock of carbonate minerals like calcite or dolomite are present, their acid-neutralizing potential helps reduce the likelihood of generating ARD.

8 The application proposes to truck dolomite rock from a site to a processing facility where magnesium metal would be extracted and the leftover rock used to manufacture cement.

9 Dolomite is a common mineral, its reserves are abundant in our country.

10 Repeatedly rinsing away these defects -- for example, with rain or tidal cycles -- allows a dolomite layer to form in only a matter of years.

11 “The structure is built of dressed dolomite limestone in Gothic Revival style,” Fuller said.

12 But in Last Chance Lake, calcium combines with plentiful carbonate as well as magnesium to form dolomite, the same mineral that forms picturesque mountain ranges.

13 Usually use magnesite, dolomite and brine as raw material to produce.

通常是用菱镁矿、白云石和卤水为原料生产的。

14 As years passed, marine sediments formed a layer of limestone known as dolomite nearly 100 feet thick.

15 Until roughly 545 million years ago, the rocks are rich in the mineral dolomite, which is believed to have formed in the oceans when oxygen levels were low, Hood says.

16 The calcium-magnesium powder produced from dolomite is not commonly used as a filler in rubber production.

由白云岩加工而成的钙镁粉，用作橡胶填料的实际生产，并不多见。

17 The commonly used fluxes are limestone and dolomite.

常用的熔剂有石灰石和白云石.

18 The structures contain a mineral called dolomite, a calcium byproduct produced by microbes that feed off methane.

19 But none of them can match the beauty of these frozen gold flames of resinous wood, twisting up from the rocky, white dolomite soil.

20 Two metres deep, the holes are burial niches, punched into the limestone and dolomite bedrock with a nine-tonne bore.
