50 DOI: 10.2747/0020-6814.50.12.1.Īgrawal S and Verma S P 2007 Comment on “Tectonic classification of basalts with classification trees” by Pieter Vermeesch (2006) Geochim. 46 575–594.Īgrawal S, Guevara M and Verma S P 2008 Tectonic discrimination of basic and ultrabasic volcanic rocks through log-transformed ratios of immobile trace elements Int. Using an analogous procedure for determining the oxidation ratios of igneous rocks as used in the SINCLAS system of Verma et al (2002, 2003), the suggested calculation scheme exactly reproduces their results except for apatite for reasons explained in the text, but with a superior match between the totals for about 11,200 analyses representing rocks of a wide range of compositionĪgrawal S, Guevara M and Verma S P 2004 Discriminant analysis applied to establish major element field boundaries for tectonic varieties of basic rocks Int. Accurate formulas along with the use of variable molecular weights for CaO and FeO corrected formula weights for apatite, pyrite and fluorite and suggested measures to avoid significant rounding off errors to achieve absolute match between the sum of the input weights of the oxides and the sum of the weights of the estimated normative minerals. The formulas are presented in a form convenient for error-free implementation in computer programs. The suggested sequence of derivation of the normative minerals greatly deviates from the sequence followed in the classical scheme. quantity-takeoff.A completely new set of formulas, based on matrix algebra, has been suggested for the calculation of the CIPW norm for igneous rocks to achieve highly consistent and accurate norms.

Estimating and costing of civil engineering projects.Link for Download the Sheet Earthwork Calculation through Excel It does not include area-wide treatment (pavement overlay and strengthening) and road resealing (pavement rehabilitation) of existing roading, normal domestic gardening practices, maintenance of roads and tracks, (along with railway tracks), the development of walking tracks, cultivation (except where re-contouring is involved), maintenance of linear network utility support structures, and maintenance (together minor realignment) of present foot tracks within public reserves and the conservation estate. Such activities comprise of, but are not restricted to, tracking, roading, cleanfill sites, cut and fill operations, quarrying and mining and re-contouring. Roading and tracking activities Earthworks involved with the construction of any new road or track or the renovation of any existing road or track devoid of general maintenance of legitimately recognized roads and track.Įarthworks - Any activity that exposes, disturbs, places or deposits land and soil. It does not also include those activities to be recognized as vegetation clearance activities. It does not include general maintenance of legitimately recognized structures, roads, tracks, and railway lines. Soil Disturbance - The disturbance of land surfaces may occur with various ways like blading, blasting, contouring, cutting of batters, excavation, ripping, root raking. Earthworks are defined as the disturbance of land surfaces with blading, contouring, ripping, moving, removing, placing or replacing soil or earth, or with the excavation, or with cutting or filling operations.
