The Table above shows structural indexes and know that the following information includes strike, dip and pitch in degrees. The reader using Tector 1994 only needs to enter the data of the Table below with MESURE, determine stress tensors with TENSOR, plot diagrams with DIAGRA, and so on. I: single phase fault populations: a new method of computing the stress tensor. Inversion of field data in fault tectonics to obtain the regional stress. 363-376, and partly in: ANGELIER J., TARANTOLA A., MANOUSSIS S. A new rapid direct inversion method by analytical means.

These examples have been published, including stress tensor results, in: ANGELIER J. Brittle structures other than faults, bedding and additional information have been discarded in these lists. The reader interested in processing the data can use the following fault slip data to check his ability to use Tector 1994 softwares (contact author for downloading executable files) or compare with other softwares. To make application easier, four very simple sets of normal fault slips are provided below and used in subsequent applications.

Tector XXI includes a specific program (SISANG) to check and translate a variety of usual formats for seismological data files. With Tector 1994, double couple focal mechanisms of earthquakes must be entered as faults. This basic information is recommended for becoming familiar with softwares, before using advanced topics (comments, comment lines, offsets, relative chronologies, coupled data, weigting, regime, etc).Ī program (ANGANG) allows conversion of a Tector 1994 data file into a Tector XXI file. Tector XXI offers three input/output modes (geological, seismological, microscopic), a correct use of which requires specific training. The examples given below show the minimum information required by Tector. For each datum, the couple of structural identifiers is followed by orientation and additional quantitative and qualitative information. Data file formats of Tector 1994 and Tector XXI differ, the latter being more flexible. The older Tector 1994 softwares used less numerous symbols (with J instead of B for bedding and * instead of ? for unknown slip sense). The Table above indicates geological structures considered in Tector XXI (inherited from Tector 2000, extinct in 2008).
