| A scintillometer could make a radiometric survey at the same time which would distinguish potassic from sodic granites. |
|
| Improving soil tilth and permeability by adding gypsum is only accomplished in sodic soils. |
|
| There is a wide range of topics which include saline, sodic, acidic, eroded, compacted, and organic soils. |
|
| There are no secondary sodic phases present, and no observed albitization of potassium feldspar, suggesting only limited Na mobility. |
|
| The Lake George center, for instance, had three emplacements, one potassic, another sodic, and yet another with a mixed composition. |
|
| The lens is tempered sodic calcic glass, 4mm thick, complying with the BS 3193 and UNI 7142 norms. |
|
| The study also indicates that the illuviation of clay particles and their subsequent accumulation in the Bt horizons have occurred in sodic environment. |
|
| It is a duplex soil classified as brown loamy earth, or sodic manganesic brown Kandosol and is also classified as Vertic Ferralsol. |
|
| Surfaces of these soils are sandy loams with strong change to medium clay subsoils that are extremely sodic in nature. |
|
| For example, the boundary between the greenschist and amphibolite facies marks a transition from amphibole of actinolitic composition to hornblende and of a sodic plagioclase into a more calcic plagioclase. |
|
| Saline and sodic waste rock is often a particular problem in arid zones, where salt in the rock is of atmospheric origin, or is interstitial and cannot be predicted from the geology. |
|
| Gold mineralization is spatially associated with the sodic intrusions and occurs as shear and tension veins or albitized quartz-carbonate ± tourmaline veinlet stockworks with pyrite. |
|
| This is followed by a reactor where the bicarbonate is injected into the off-gases brought to at least 140°C. Neutralisation produces sodic salts in powder form. |
|
| Because the reclamation of sodic soils involves not only leaching out the soluble salts but also replacing exchangeable sodium with calcium and improving the physical properties of the soils. |
|
| Langbeinite is a new chemical amendment for the reclamation of sodic and saline sodic soils. |
|
| Both soils are fine, smectic, hyperthermic Sodic Hapluserts. |
