Several faults in south-central New Hampshire can be extended into Massachusetts (MA) as a result of detailed mapping in both states since publication of the MA state bedrock geologic map in 1983. Many of these faults delineate and/or cut Devonian metamorphic isograds in the Silurian Merrimack Belt in northern MA, and juxtapose chlorite-grade rocks in the Nashua sub-belt (NSB) between lithologically similar middle- to upper amphibolite-facies rocks on either side.

Recent mapping in the NSB, combined with previous studies, suggest it may represent a graben initially formed during latest Paleozoic transtension contemporaneous with formation of the Narragansett Basin in southeastern MA and RI. Mylonites along the Silver Hill-Wekepeke Fault (Robinson, 1981), bounding the western edge of the NSB, show east-side-down normal motion and west-side down normal motion along the Clinton-Newbury Fault Zone (CNFZ; Goldstein, 1994) which bounds the NSB{\textquoteright}s southeastern margin. A possible extension of the Flint Hill fault system (NH) forms the eastern edge of the NSB offsetting the CNFZ with normal west-side down motion near Ayer, MA. Late brittle normal faults in the NSB are abundant.\ Late, low-To, west-side-down shear zones in the Nashoba Terrane and similar rocks to the south may also be related to down-dropping of the NSB.

AFT ages were collected across north-central MA to constrain its late uplift history. A ~127 Ma AFT age in the NSB is discontinuous with AFT ages in the belts adjoining it, with ~182-144 Ma ages west across the Wekepeke fault and ~160-167 Ma east across the CNFZ. To the west, the brittle southern extension of the Pinnacle Fault in NH (Stodge Meadow Pond fault of Peterson, 1984) follows the western edge of the Fitchburg plutons in MA while a well-exposed west-side down brittle normal fault system, possibly the southward extension of the Campbell Hill Fault (NH), is developed along their eastern edge. AFT ages of ~144-136 Ma immediately west of the Pinnacle Fault in MA are discontinuous with ~117-115 Ma ages immediately to the east within the Fitchburg plutons. A single ~106 Ma age in the plutons west of the Campbell Hill Fault in MA is discontinuous with ~128-123 Ma ages to the east of it. The discontinuities amongst AFT ages across these faults suggest that they may have been active through the Cretaceous.

These are among the largest landslides to occur in Massachusetts since 1901. Tropical storm Irene dropped 180-250+ mm of rain in a 12 to 15-hour period on the Deerfield watershed preceded by 130-180 mm of rain in the 1.5 weeks leading up to Irene. Soils were saturated, an unusual condition for the month of August, and probably contributed significantly to slope failure. The three translational slides occurred at approximately 10 am on August 28, 2011, involved 765 m of slope at an average angle of 28-33 degrees , covered an area of 1.2 ha and moved about 7645 m (super 3) of material. Bedrock sheeting joints oriented parallel to the slope (284 degrees , 38-40 degrees dip) provided the slip surface upon which the overlying 0.6-1.2 m of colluvium and glacial till slid. The rotational slide occurred along an unarmored section of the Cold River. The slip surface was a 4-8 foot thick layer of laminated lake-bottom sediments overlain by 12-19 feet of stream terrace and debris flow/alluvial fan deposits transported by Trout Brook, a smaller tributary to the Cold River. This section of Route 2 has experienced chronic failures beginning with the storm of 1938. The cost to repair this six-mile section of Route 2 was $22.5 million. Flooding within the Deerfield watershed was extreme with a record-breaking peak flow of 3100 m (super 3) /s (72 year record) where the Deerfield enters the Connecticut River. Approximately 1.6x10 (super 8) m (super 3) of water was discharged through the Deerfield during the event indicating that approximately 112 mm of Irene{\textquoteright}s rainfall was converted directly to runoff, a yield of between 45\% and 62\%. Clays and silts locked in storage in the glacial sediments within the watershed were mobilized resulting in record-breaking sediment loads 5-times greater than predicted from the pre-existing rating curve. Approximately 1.2 Mtonnes of sediment was discharged by the river during Irene. Where the Deerfield and Connecticut Rivers meet, the Deerfield watershed area is one tenth the size of the Connecticut River, yet the Deerfield produced as much as 40\% of the total sediment observed on the lower Connecticut.}, keywords = {$\#$Landslides, $\#$NaturalHazards, $\#$StaffPubs, Cold River, Deerfield Watershed, effects, Environmental geology, geologic hazards, Irene, landslide, landslides, mass movements, massachusetts, natural hazards, storms, Tropical Storm Irene, United States, western Massachusetts}, isbn = {00167592}, url = {https://gsa.confex.com/gsa/2013NE/webprogram/Paper215998.html}, author = {Stephen B Mabee and Jonathan D Woodruff and Fellows, John and Joseph P Kopera} } @proceedings {308, title = {Lineaments; their value in assessing regional groundwater availability and quality in bedrock aquifers of glaciated metamorphic terrains; a case study}, volume = {25}, year = {1993}, note = {Accession Number: 1993-017600; Conference Name: Geological Society of America, Northeastern Section, 28th annual meeting; Burlington, VT, United States; Conference Date: 19930322; Language: English; Coden: GAAPBC; Collation: 1; Collation: 35; Publication Types: Abstract Only; Serial; Conference document; Updated Code: 1993; Monograph Title: Geological Society of America, Northeastern Section, 28th annual meeting; Monograph Author(s): Anonymous; Reviewed Item: Analytic}, month = {1993/03/01/}, pages = {35 - 35}, publisher = {Geological Society of America (GSA) : Boulder, CO, United States}, address = {United States}, keywords = {$\#$StaffPubs, amphibolite, aquifers, Atlantic Coastal Plain, BEDROCK, central Maine, fractures, Georgetown Maine, ground water, hydraulic conductivity, hydrogeology, lineaments, Maine, metamorphic rocks, structural controls, United States, water quality}, isbn = {00167592}, issn = {0016-7592}, author = {Stephen B Mabee} } @booklet {242, title = {Land area potentially affected by sea level rise along the Massachusetts coast}, howpublished = {Open-File Report}, year = {2006}, publisher = {Massachusetts Geological Survey}, edition = {OFR-06-01}, keywords = {$\#$MGSPub, $\#$Misc, climate change, coast, flooding, sea level rise}, url = {http://www.geo.umass.edu/stategeologist/}, author = {Joseph P Kopera and Steven A Nathan} } @mastersthesis {307, title = {Lineaments; their value in assessing groundwater availability and quality in bedrock aquifers of glaciated metamorphic terrains; a case study}, year = {1992}, note = {Accession Number: 1993-003224; Educational Institutions: University of Massachusetts at Amherst : Amherst, MA, United States; Language: English; Collation: 592; Type of Degree: Doctoral; Publication Types: Thesis or dissertation; Updated Code: 1993; Reviewed Item: Monograph}, month = {1992/01/01/}, address = {United States}, keywords = {$\#$StaffPubs, aerial photography;, aquifers;, bedrock;, case studies;, fractures;, Georgetown Maine;, ground water;, Hydrogeology; 21, lineaments;, Maine;, outcrops;, Sagadahoc County Maine;, SLAR;, Structural geology; 16, terrains;, United States;, water quality;, water wells;, wells;}, url = {http://silk.library.umass.edu/login?url=http://search.ebscohost.com/login.aspx?direct=true\&db=geh\&AN=1993-003224\&site=ehost-live\&scope=site}, author = {Stephen B Mabee} } @online {166, title = {Learning from the Fossil Record}, publisher = {UC Berkeley}, abstract = {Book originally published by the Paleontological Society.
