Additional information This page is used on multiple pages and has complex logic so any alteration should be checked as a minor typo can break display. It was noted that many articles appeared to have names that were not consistent with wikipedia name capitalisation style. This has been accounted for in page logic so page logic should not break. Map data is approximate surface projection of fracture zones (orange) on oceans. Associated features such as probable extension of fracture zones are lighter orange and mid oceanic ridges are white. Switching logic is used to emphasise particular data such as use of colour violet or to select out a portion of the data file (this has less rendering overhead). It is probably best not to add local features via switching logic to this file. An example of how to add local features in later rendered layers is found at Boomerang Seamount.

Clicking on the map enables mouse over that displays more information as well as the fracture zone name.

The map has been checked against sea floor contours and at least one reference for position. Experience has shown that original acaedemic papers often are more accurate sources, so improvements are possible. These sources often have slightly different feature information, lengths of the zone and specify transform faults not originally mapped. The feature length data is approximate and may deviate from references, sometimes because they can not agree. Academic work on zones consulted during preparation of data is not necessarily acknowledged where there was relatively minor difference in data. The data is incomplete as official recognition of feature names is a drawn out process. Unofficial names have been added from academic literature and this remains a work in progress particularly for Indian Ocean and Eastern Pacific where a number of officially unnamed fracture zones exist and mapping is still ongoing. Unoffical names are used if more than once acaedemic source uses same names. The sources for most of the data and significant revisions are:

Logic has been added to display distinctive fracture zones and mid-ocean ridges. The data base has now evolved to better define some of these features from original sources and now has an existence of its own with improvements. As it was not appropriate to develop all improvements to the json database on this page itself for several technical reasons a subpage with all the json code before logic insertion had been created and any other users improving the database could use it to test json updates at ->Wikipedia:Map data/Fracture zone/json. However take care as the code for the two pages could easily get out of sync. Logic changes do have to be inserted in the live page although of course should be tested where long code snippits as these more likely to have typos.
